TS924 RAIL TO RAIL HIGH OUTPUT CURRENT QUAD OPERATIONAL AMPLIFIER ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ RAIL TO RAIL INPUT AND OUTPUT LOW NOISE : 9nV/√(Hz) LOW DISTORTION HIGH OUTPUT CURRENT : 80mA (able to drive 32Ω loads) HIGH SPEED : 4MHz, 1.3V/µs OPERATING FROM 2.7V to 12V LOW INPUT OFFSET VOLTAGE : 900µVmax (TS924A) ESD INTERNAL PROTECTION : 2KV LATCH-UP IMMUNITY MACROMODEL INCLUDED IN THIS SPECIFICATION N DIP14 (Plastic Package) 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.
