OPA137N from Texas Instruments, in a SOT-23-5. 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 | Out | output | Amplifier output, swings to (V-)+1.2V and (V+)-1.1V with a 10kΩ load at VS = ±15V and is short-circuit current limited to -25/+60mA. |
| 2 | V- | power_in | Negative supply; total supply (V+ to V-) is ±2.25V to ±18V (+4.5V to +36V single supply), bypassed with a ceramic capacitor of 10nF or larger. |
| 3 | +In | input | Non-inverting input, with common-mode range from (V-)+3V up to V+ and typical bias current of ±10pA. |
| 4 | -In | input | Inverting input, with common-mode range from (V-)+3V up to V+ and input current limited to 2mA when the voltage exceeds supply by the diode clamp. |
| 5 | V+ | power_in | Positive supply; total supply (V+ to V-) is ±2.25V to ±18V (+4.5V to +36V single supply) with 36V absolute maximum, bypassed with a ceramic capacitor of 10nF or larger. |
