High-voltage, rail-to-rail, dual-channel operational amplifier with thermal shutdown and output current limiter


The TSB582 is a high performance dual operational amplifier featuring high supply voltages and high output current capability while being protected through internal current limiting and thermal shutdown.

The TSB582 is a unity gain stable, dual operational amplifier with high current capability, featuring internal protections against overtemperature and current overload conditions for both industrial and automotive applications.

In addition, the TSB582 has enhanced ESD and RF noise immunity. It typically outputs up to 200 mA per channel to drive low resistance inductive loads such as angle resolvers, lineout cables and piezo actuators.
