QUAD OP-AMP TS925: OPTIMUM
FOR AUDIO


ST's TS925 low power input and output rail-to-rail operational amplifier mainly targets consumer applications such as CD, CD-ROM and DVD multimedia systems, among others.

Operating from 2.7V to 12V (specification is issued at 3V and 5V), the TS925 is housed DIP/SO/TSSOP16 package and delivers a typical output current of 80mA, allowing the drive of 16 omega loads (headphone output).

The stability of the TS925 is ensured with capacitive loads up to 100pF. In standby mode total supply current drops to less than 10µA when active and a phantom ground at Vcc/2, avoiding having to resort to an external voltage.

The TS925 is protected against electrostatic discharges up to 2000V and is immunized against latch-up. The TS925 is part of the TS92xx series which includes dual (TS922) and quad (TS924) op amps.
