OPA548FKTWT 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 (V-) - 0.1 V to (V+) - 3 V and input bias current -100 to -500 nA. |
| 2 | VIN- | power_in | Inverting input with common-mode voltage range (V-) - 0.1 V to (V+) - 3 V and input bias current -100 to -500 nA. |
| 3 | ILIM | input | Current limit control input setting output current from 0 A to 5 A via equation ILIM = (15000)(4.75) / (13750 Ω + RCL) using external resistor or DAC. |
| 4 | V- | power_in | Negative power supply with operating voltage range 8 V to 60 V (±4 V to ±30 V dual-supply) and quiescent current ±17 mA to ±20 mA typical. |
| 5 | V+ | power_in | Positive power supply with operating voltage range 8 V to 60 V (±4 V to ±30 V dual-supply). |
| 6 | VO | output | High-current output with maximum continuous current ±3 A DC or 3 Arms AC and output voltage limited by supply and load current. |
| 7 | E/S | bidirectional | Enable/status pin disabling output when pulled below (V-) + 0.8 V and indicating thermal shutdown status when monitored, with 1 µs disable time and 3 µs enable time. |
| 8 | TAB | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
