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 Ω and 100 Ω loads
■Low supply current: 200 μA/ampli (VCC = 3 V)
■Latch-up immunity
■Spice macromodel included in this specification
Description
The TS914 is a rail-to-rail CMOS quad
operational amplifier designed to operate with a
single or dual supply voltage.
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 kΩ, and VCC- +350 mV,
VCC+ -350 mV, with RL = 600 Ω.
This product offers a broad supply voltage
operating range from 2.7 to 16 V and a supply
current of only 200 μA/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.

5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ 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 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.

4 Macromodels
4.1 Important note concerning this macromodel
●All models are a trade-off between accuracy and complexity (that is, simulation time).
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 Ta bl e 6 are derived from this macromodel.
