Description

The TS924 is a rail-to-rail quad BiCMOS operational amplifier optimized and fully specified for 3 V and 5 V 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.
