OPA548F from Texas Instruments, in a TO-263-7. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN+ | power_in | Noninverting input with common-mode voltage range from (V-) - 0.1 V to (V+) - 2.3 V |
| 2 | VIN- | power_in | Inverting input with common-mode voltage range from (V-) - 0.1 V to (V+) - 2.3 V |
| 3 | ILIM | input | Current limit control input; connect resistor RCL between ILIM and V- to set output current limit from 0 A to 5 A per ILIM = (15000)(4.75) / (13750 Ω + RCL) |
| 4 | V- | power_in | Negative power supply; supports supply voltage of 8 V to 60 V (single supply) or ±4 V to ±30 V (dual supply) |
| 5 | V+ | power_in | Positive power supply; supports supply voltage of 8 V to 60 V (single supply) or ±4 V to ±30 V (dual supply) |
| 6 | VO | output | Amplifier output with maximum continuous current of ±3 A DC and 3 Arms AC; output voltage swing limited by supply voltage and load impedance |
| 7 | E/S | bidirectional | Enable/disable control and thermal shutdown status output; pull to ≤ (V-) + 0.8 V to disable output (1 µs disable time) or ≥ (V-) + 2.4 V to enable output (3 µs enable time); thermal shutdown engages at 160°C and resets at 140°C |
| 8 | TAB | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
