Description

TS922 and TS922A devices are rail-to-rail dual BiCMOS operational amplifiers optimized and fully specified for 3 V and 5 V operation. These devices have high output currents which allow low-load impedances to be driven. Very low noise, low distortion, low offset, and a high output current capability make these devices an excellent choice for high quality, low voltage, or battery operated audio systems. The devices are stable for capacitive loads up to 500 pF.
