TS982
Wide bandwidth dual bipolar operational amplifier
Features
■ Operating from VCC = 2.5 V to 5.5 V
■ 200 mA output current on each amplifier
■ High dissipation package
■ Rail-to-rail input and output
■ Unity-gain stable
Applications
■ Hall sensor compensation coil
■ Servo amplifier
■ Motor driver
■ Industrial
■ Automotive
Description
The TS982 is a dual operational amplifier able to
drive 200 mA down to voltages as low as 2.7 V.
The SO-8 exposed-pad package allows high
current output at high ambient temperatures
making it a reliable solution for automotive and
industrial applications.
The TS982 is stable with a unity gain.
