TS914, TS914A Rail-to-rail CMOS quad operational amplifier Features Rail-to-rail input and output voltage ranges Single (or dual) supply operation from 2.7 to 16 V Extremely low input bias current: 1 pA typ Low input offset voltage: 5 mV max. (A grade) Specified for 600 and 100 loads Low supply current: 200 A/ampli (VCC = 3 V) Latch-up immunity Spice macromodel included in this specification D SO-14 (Plastic micropackage) Pin connections (top view) Description The TS914 is a rail-to-rail CMOS quad operational amplifier designed to operate with a single or dual supply voltage. Output 1 1 Inverting Input 1 2 14 Output 4 Non-inverting Input 1 3 V CC + 4 Non-inverting Input 2 5 + + 10 Non-inverting Input 3 Inverting Input 2 6 - - 9 Inverting Input 3 Output 2 7 8 Output 3 - - 13 Inverting Input 4 + + 12 Non-inverting Input 4 11 VCC - The input voltage range Vicm includes the two supply rails VCC+ and VCC-. The output reaches VCC- +50 mV, VCC+ -50 mV, with RL = 10 k, and VCC- +350 mV, VCC+ -350 mV, with RL = 600 . This product offers a broad supply voltage operating range from 2.7 to 16 V and a supply current of only 200 A/amp (VCC = 3 V). The source and sink output current capability is typically 40 mA (at VCC = 3 V), fixed by an internal limitation circuit.

All voltage values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of input and output voltages must never exceed VCC+ +0.3 V. 4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuit on all amplifiers. These are typical values. 5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating. 7. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 2.

Macromodels are not a substitute for breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the nominal performance of a typical device within specified operating conditions (such as temperature or supply voltage, etc). Thus, the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels used outside of the specified conditions (such as VCC, or temperature) or even worse, outside of the device's operating conditions (such as VCC or Vicm) is not reliable in any way. The values provided in Table 6 are derived from this macromodel. Table 6.
