TS922H RAIL TO RAIL HIGH OUTPUT CURRENT DUAL 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 : 3.0mVmax ESD INTERNAL PROTECTION : 2KV LATCH-UP IMMUNITY 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. die Form PAD CONNECTION APPLICATIONS ■ ■ ■ ■ ■ ■ OUT1 ORDER CODE IN1 - headphone amplifier piezoelectric speaker driver sound cards MPEG boards, multimedia systems, ... line driver, buffer cordless telephones and portable communication equipment ■ instrumentation with low noise as key factor Part Number JTS922H-DZD1 Temperature Range -40°C, +150°C Vcc+ OUT2 IN2- Package Die IN1 + Vcc- IN2+ • Die = Wafer Form ( not sawed) September 2003 1/6 TS922H ABSOLUTE MAXIMUM RATINGS Symbol VCC Vid Parameter Supply voltage 1) Differential Input Voltage 2) 3) Vi Input Voltage Tj Maximum Junction Temperature Output Short Circuit Duration 1. 2. 3. 4. Value Unit 14 V ±1 V -0.3 to 14 V 155 °C see note 4) S All voltages values, except differential voltage are with respect to network ground terminal. Differential voltagesare 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 OPERATING CONDITIONS Symbol Parameter VCC Supply voltage Toper Operating Free Air Temperature Range Vicm Common Mode Input Voltage Range 2/6 Value Unit 2.7 to 12 V -40 to +150 °C VCC- -0.2 to VCC+ +0.2 V TS922H ELECTRICAL CHARACTERISTICS VCC+ = 3V, Tamb = 25°C (unless otherwise specified) Symbol Parameter Min.
