Description

The TS922 is a rail-to-rail dual BiCMOS

operational amplifier optimized and fully specified

for 3 and 5 V operation.

The device’s high output current allows low-load

impedances to be driven.

Very low noise, low distortion, low offset and a

high output current capability make this device an

excellent choice for high quality, low voltage or

battery operated audio systems.

The device is stable for capacitive loads up to

500 pF.

TS922, TS922A Macromodel 4 Macromodel 4.1 Important note concerning this macromodel ● All models are a trade-off between accuracy and complexity (i.e. simulation time). ● Macromodels are not a substitute to 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 (temperature, supply voltage, for example).
