TS925AIPT

Instrumentation, Op Amps, Buffer Amps Overview

The TS925AIPT is a quad rail-to-rail BiCMOS operational amplifier optimized for 3V and 5V operation. It features a 4 MHz gain bandwidth product, 1.3 V/µs slew rate, and 80 mA output current capability. The device operates from 2.7V to 12V with low noise of 9 nV/√Hz. The 'A' suffix indicates a maximum input offset voltage of 900 µV at 25°C. It includes an adjustable phantom ground (VCC/2) and a standby mode reducing consumption to 6 µA.
