With a 10V/µs slew rate and 1 MHz gain-bandwidth product, this amplifier drives inductive loads like motors, actuators, and valve coils without the slew-rate limiting that a general-purpose op-amp would impose on a fast edge. Rated for -40°C to 85°C operation, the part suits industrial environments where the ambient temperature inside a control cabinet can exceed 60°C. ## What the key ratings mean for your BOM fit The 5 A continuous output current is the headline figure — this op-amp directly drives a DC motor, a Peltier cooler, or a solenoid without an external booster stage, as long as the thermal dissipation in the TO-220-7 package is managed with a heatsink. Input offset voltage is 2 mV typical, and input bias current is 100 nA — the DC accuracy is adequate for current-sense and servo loops where the signal is in the millivolt range, but not for precision microvolt-level measurements. Quiescent supply current of 17 mA is the no-load draw — at full 5 A output, the total supply current is dominated by the load, not the amplifier's internal bias. ## Package and mounting: TO-220-7 through-hole The TO-220-7 package is a 7-lead through-hole power package with a metal tab for heatsink attachment — the tab is internally connected to the negative supply rail (V-), so the heatsink must be electrically isolated or the rail must be system ground. Supplied in Tube packaging, the parts are handled as individual units for manual or wave-solder assembly — not tape-and-reel for automated pick-and-place.","metaTitle":"OPA548T-1 Power Op-Amp, TO-220-7, 5 A Output","metaDescription":"OPA548T-1 power operational amplifier, 5 A output, 10V/µs slew rate, 1 MHz GBW, TO-220-7 package.
