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 distor-

tion, low offset and high output current capability

making this device an excellent choice for high

quality, low voltage or battery operated audio sys-

tems.

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
