Technical details

Power op-amp for industrial actuator and valve drives

Its headline rating is 750 mA output current per channel, paired with a supply span from 8 V to 60 V — that puts it squarely in the territory of driving DC motors, solenoid valves, piezoelectric actuators, and high-current audio transducers. The 6 V/µs slew rate and 1 MHz gain-bandwidth product are modest by signal-chain standards, but they are sized for the inductive and capacitive loads a power stage handles, not for fast-settling ADC front ends. The TO-220-7 package with formed leads is a through-hole power package — the metal tab is the thermal path, not an afterthought. Plan for a heatsink if the output current is sustained above a few hundred milliamps; the tab is electrically connected to the negative supply rail (V–), so an insulating pad or mica washer is needed if the heatsink is chassis-grounded.

The 750 mA per channel rating is the continuous DC output capability at the package limit.

Mounting and thermal management

Through-hole TO-220-7 with formed leads — the leads are pre-formed for vertical PCB mounting, and the tab is the primary heat path.
