TS922, TS922A Datasheet Rail-to-rail, high output current, dual operational amplifier Features Rail-to-rail input and output Low noise: 9 nV/Hz Low distortion Flip-chip with backcoating High output current: 80 mA (able to drive 32 loads) High-speed: 4 MHz, 1 V/s Operating from 2.7 to 12 V Low input offset voltage: 900 V max. (TS922A) ESD internal protection: 2 kV Latch-up immunity SO8 Applications Line drivers and actuator drivers Portable speakers Instrumentation with low noise as key factor Multimedia systems and portable equipments TSSOP8 Description The TS922 and the TS922A devices are rail-to-rail dual BiCMOS operational amplifiers optimized and fully specified for 3 V and 5 V operations. These devices have high output currents which allow low-load impedances to be driven. Product status link Very low noise, low distortion, low offset, and a high output current capability make TS922 and TS922A 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.
