® RAIL TO RAIL HIGH OUTPUT CURRENT QUAD OPERATIONAL AMPLIFIER - - . . RAIL TO RAIL INPUT AND OUTPUT LOW NOISE : 9n V/ √ Hz  LOW DISTORTION HIGH OUTPUT CURRENT : 80m A (able to drive 32Ω loads) HIGH SPEED : 4MHz, 1.3V/µs OPERATING FROM 2.7V TO 12V LOW INPUT OFFSET VOLTAGE : 900µV max. (TS925A) ADJUSTABLE PHANTOM GROUND (VCC/2) STANDBY MODE N DIP16 (Plastic Package) D SO16 (Plastic Micropackage) ESD INTERNAL PROTECTION : 2k V LATCH-UP IMMUNITY MACROMODEL INCLUDED IN THIS SPECIFICATION P TSSOP16 (Thin Shrink Small Outline Package) DESCRIPTION The TS925 is a RAIL TO RAIL quad Bi CMOS operational amplifier optimized and fully specified for 3V and 5V operation. High output current allows low load impedances to be driven. An internal low impedance PHANTOM GROUND eliminates the need for an external reference voltage or biasing arrangement. The TS925 exhibits a very low noise, low distortion and high output current making this device an excellent choice for high quality, low voltage or battery operated audio/tele systems. The device is stable for capacitive loads up to 500p F. When the STANDBY mode is enabled, the total consumption drops to 6µA (VCC = 3V).
