RAIL TO RAIL INPUT AND OUTPUT LOW NOISE : 9nV/ ) (Hz) LOW DISTORTION HIGH OUTPUT CURRENT : 80mA (able to drive 32 loads) HIGH SPEED : 4MHz, 1.3V/s OPERATING FROM 2.7V to 12V LOW INPUT OFFSET VOLTAGE : 900V max (TS922A) ESD INTERNAL PROTECTION : 2KV LATCH-UP IMMUNITY MACROMODEL INCLUDED IN THIS SPECIFICATION N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) P TSSOP8 (Thin Shrink Small Outline Package) ORDER CODES Part Number Temperature Range -40, +125oC Package N * D * P * 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 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.

Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The magnitude of input and output voltages must never exceed VCC+ +0.3V. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.
