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.

TS922, TS922A 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) ...
