TS914
Rail-to-rail CMOS quad operational amplifier
Features
■Rail-to-rail input and output voltage ranges
■Single (or dual) supp ly op er at ion from 2. 7V to
16V
■Extremely low inp ut bias current: 1pA typ
■Low input offset volt age: 5mV max.
■Specified for 600Ω and 100Ω loads
■Low supply current: 200μA/ampli (VCC = 3V)
■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 rea ches:
■VCC- +50mV, VCC+ -50mV, with RL = 10kΩ
■VCC- +350mV, VCC+ -350mV, with RL = 600Ω
This product of fers a broad supply voltage
operating range from 2.7V to 16V and a supply
current of only 20 0μA/amp (VCC = 3V).
Source and sink output current capability is
typically 40mA (at VCC = 3V), fixed by an internal
limitation circuit.

4.1 Important note concerning this macromodel
Please consider the following remarks before using this macromodel:
●All models are a trade-off between accuracy and complexity (i.e. simulation time).
Macromodels a re no t a sub sti t ute for breadboar din g; rather, they conf irm the validity of
a design approach and help to select surrounding component values.
●A macromodel em ulates the nominal perf ormance of a typical de vice 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 ou tside of the specif ied conditions (such as V CC,
or temperature) or even worse, outside of the device’s operating conditions (such as
VCC or Vicm) is not reliable in any way.
The v alues provided in Table 6 are de rived from this macrom o de l.
