These miniature, low-cost amplifiers are designed to operate on single supplies from 1.8V (0.9V) to 5.5V (2.75V). Applications include sensor amplification and signal conditioning in battery-powered systems. The OPA363 and OPA364 families offer excellent CMRR without the crossover associated with traditional complimentary input stages. This results in excellent performance for driving Analog-to-Digital (A/D) converters without degradation of differential linearity and THD. The input commonmode range includes both the negative and positive supplies. The output voltage swing is within 10mV of the rails. APPLICATIONS The OPA363 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1A.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less.

The OPA363 features an additional pin for shutdown/ enable function. These families do not exhibit phase reversal and are unity-gain stable. Specified over the industrial temperature range of -40C to +125C, the OPA363 and OPA364 families offer precision performance for a wide range of applications. VCC + 1.8V IBIAS Patent Pending Very Low Ripple Topology IBIAS RAIL-TO-RAIL INPUT The OPA363 and OPA364 feature excellent rail-to-rail operation, with supply voltages as low as 0.9V. The input common-mode voltage range of the OPA363 and OPA364 family extends 100mV beyond supply rails. The unique input topology of the OPA363 and OPA364 eliminates the input offset transition region typical of most rail-to-rail complimentary stage operational amplifiers, allowing the OPA363 and OPA364 to provide superior common-mode performance over the entire common-mode input range, as seen in Figure 1. This feature prevents degradation of the differential linearity error and THD when driving A/D converters. A simplified schematic of the OPA363 and OPA364 is shown in Figure 2.

Single 0.1F bypass capacitors should be placed across supply pins and as close to the part as possible. Supply voltages higher than 5.5V (absolute maximum) may cause permanent damage to the amplifier. Many specifications apply from -40C to +125C.

A logic level HIGH enables the op amp. A valid logic HIGH is defined as voltage > 75% of the positive supply applied to the enable pin. The valid logic HIGH signal can be as much as 5.5V above the negative supply, independent of the positive supply voltage. A valid logic LOW is defined as < 0.8V above the negative supply pin. If dual or split power supplies are used, care should be taken to ensure logic input signals are properly referred to the negative supply voltage. This pin should be connected to a valid high or low voltage or driven, not left open circuit. All OPA363 and OPA364 pins are static protected with internal ESD protection diodes tied to the supplies. These diodes will provide overdrive protection if the current is externally limited to 10mA, as stated in the absolute maximum ratings and shown in Figure 4. The logic input is a high-impedance CMOS input. Dual op amps are provided separate logic inputs. For battery-operated applications, this feature may be used to greatly reduce the average current and extend battery life. The enable time is 20s; disable time is 1s. When disabled, the output assumes a high-impedance state. This allows the OPA363 to be operated as a "gated" amplifier, or to have its output multiplexed onto a common analog output bus. CAPACITIVE LOAD The OPA363 and OPA364 series op amps can drive a wide range of capacitive loads. However, all op amps under certain conditions may become unstable. Op amp configuration, gain, and load value are just a few of the factors to consider when determining stability. An op amp in unity-gain configuration is the most susceptible to the effects of capacitive load. The capacitive load reacts with the output resistance of the op amp to create a pole in the small-signal response, which degrades the phase margin. In unity gain, the OPA363 and OPA364 series op amps perform well with a pure capacitive load up to approximately 1000pF. The ESR (Equivalent Series Resistance) of the loading capacitor may be sufficient to allow the OPA363 and OPA364 to directly drive very large capacitive loads (> 1F). Increasing gain enhances the amplifier's ability to drive more capacitance. See the typical characteristic "Small-Signal Overshoot vs Capacitive Load." One method of improving capacitive load drive in the unitygain configuration is to insert a 10 to 20 resistor in series with the output, as shown in Figure 3. This significantly reduces ringing with large capacitive loads. However, if there is a resistive load in parallel with the capacitive load, it creates a voltage divider introducing a dc error at the output and slightly reduces output swing. This error may be insignificant. For instance, with RL = 10k and RS = 20, there is only about a 0.2% error at the output.

ACHIEVING OUTPUT SWING TO THE OP AMP'S NEGATIVE RAIL Some applications require an accurate output voltage swing from 0V to a positive full-scale voltage. A good single supply op amp may be able to swing within a few mV of single supply ground, but as the output is driven toward 0V, the output stage of the amplifier will prevent the output from reaching the negative supply rail of the amplifier. The output of the OPA363 or OPA364 can be made to swing to ground, or slightly below, on a single supply power source. To do so requires use of another resistor and an additional, more negative power supply than the op amp's negative supply. A pulldown resistor may be connected between the output and the additional negative supply to pull the output down below the value that the output would otherwise achieve as shown in Figure 5. V+ = +5V OPA363 OPA364 VOUT VIN 500A Op Amp's Negative Supply Grounded RP = 10k -V = -5V (Additional Negative Supply) FIGURE 5. OPA363 and OPA364 Swing to Ground. This technique will not work with all op amps. The output stage of the OPA363 and OPA364 allows the output voltage to be pulled below that of most op amps, if approximately 500A is maintained through the output stage. To calculate the appropriate value load resistor and negative supply, RL = -V/500A. The OPA363 and OPA364 have been characterized to perform well under the described conditions, maintaining excellent accuracy down to 0V and as low as -10mV. Limiting and nonlinearity occur below -10mV, with linearity returning as the output is again driven above -10mV. FIGURE 3. Improving Capacitive Load Drive. OPA363, 2363, 364, 2364, 4364 SBOS259B www.ti.com 9 BUFFERED REFERENCE VOLTAGE Many single-supply applications require a mid-supply reference voltage. The OPA363 and OPA364 offer excellent capacitive load drive capability, and can be configured to provide a 0.9V reference voltage, as can be seen in Figure 6.

DIRECTLY DRIVING THE ADS8324 AND THE MSP430 FIGURE 8. Driving the 12-Bit A/D Converter on the MSP430. The OPA363 and OPA364 series op amps are optimized for driving medium speed (up to 100kHz) sampling A/D converters. However, they also offer excellent performance for higher speed converters. The no crossover input stage of the OPA363 and OPA364 directly drive A/D converters without degradation of differential linearity and THD. They provide an effective means of buffering the A/D converters input capacitance and resulting charge injection while providing signal gain. Figure 7 and Figure 8 show the OPA363 and OPA364 configured to drive the ADS8324 and the 12-bit A/D converter on the MSP430. AUDIO APPLICATIONS The OPA363 and OPA364 op amp family has linear offset voltage over the entire input common-mode range. Combined with low-noise, this feature makes the OPA363 and OPA364 suitable for audio applications. Single supply 1.8V operation allows the OPA2363 and OPA2364 to be optimal candidates for dual stereo-headphone drivers and microphone pre-amplifiers in portable stereo equipment, see Figures 9 and 10. 20k V+ 1F 20k One of Right or Left Channel 20k 20k 1/2 OPA2363 V+ 10k V- 1/2 TPS6100 47pF 10k One of Right or Left Headphone Out V- Internally Biased V- FIGURE 9.
