Description
The TS924 is a rail-to-rail quad BiCMOS operational amplifier optimized and fully specified for 3V and 5V operation.
High output current allows low load impedances to be driven.
The TS924 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
■
MPEG boards, multimedia systems,...
■Line driver, buffer
■Cordless telephones and portable communication equipment
