Product details

Power op-amp for high-current loads

Its wide supply span suits it for 12 V, 24 V, and 48 V industrial systems — motor drives, solenoid actuators, valve control, and audio amplifier output stages. The 1 MHz gain-bandwidth product and 10 V/µs slew rate are adequate for PWM drive signals up to several hundred kilohertz and for audio-frequency linear amplification.

Housed in a DDPAK/TO-263-7 surface-mount package (7 leads plus exposed tab), the OPA548F/500 requires a thermal pad on the PCB to dissipate heat from the 5 A output stage. The tab is the main thermal path — a via-stitched copper plane under the tab is expected for continuous operation near the 5 A limit.

Supply current and input offset

Quiescent supply current is 17 mA, which is modest for a 5 A-capable amplifier and keeps self-heating low at idle.

Frequently asked questions

Is OPA548F/500 obsolete?

There is no announced end-of-life or last-time-buy schedule.

What is the output current of OPA548F/500?

The OPA548F/500 can deliver 5 A per channel continuously. This is the headline rating that defines its application space — motor drives, actuators, and audio output stages.

What is the equivalent part for OPA548F/500?

The THS4215DRBT is a higher-speed voltage-feedback amplifier (350 MHz, 970 V/µs) but is not a functional replacement — it lacks the 5 A output capability and wide supply range of the OPA548F/500.
