DESCRIPTION

The TS922 is a RAIL TO RAIL dual BiCMOS

operational amplifier optimized and fully specified

for 3V and 5V operation.

High output current allows low load impedances to

be driven.

The TS922 exhibits a very low noise, low distortion,

low offset and high output current capability making

this device an excellent choice for high quality, low

voltage or battery operated audio systems.

The device is stable for capacitive loads up to

500pF.

APPLICATIONS

headphone amplifier

piezoelectric speaker driver

sound cards, multimedia systems

line driver, actuator driver

servo amplifier

mobile phone and portable equipment

instrumentation with low noise as key factor

Notes :

1. All voltage values, except differential voltage are with respect to network ground terminal.

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3. The magnitude of input and output voltages must never exceed V

+0.3V.

4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
