Description
The TS914 device 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.

4 Macromodels
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 Table 6 are derived from this macromodel.
