OPA657N 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 | VOUT | output | Output of the amplifier, specified with a high output current of 70 mA in the datasheet features list. |
| 2 | -VS | power_in | Negative power supply; total supply voltage is limited to ±6.5 V absolute maximum, with 8 V to 12 V total recommended. |
| 3 | VIN+ | power_in | Noninverting input; input voltage must stay between -VS and +VS per the absolute maximum ratings. |
| 4 | VIN- | power_in | Inverting input; input voltage and differential input voltage are limited to -VS to +VS per the absolute maximum ratings. |
| 5 | +VS | power_in | Positive power supply; total supply voltage is limited to ±6.5 V absolute maximum, with 8 V to 12 V total recommended. |
