OPA237NA from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; not used by the die. |
| 2 | -IN | input | Inverting input of the op-amp. High-impedance analog input (differential 5 MΩ |
| 3 | +IN | input | Noninverting input of the op-amp. High-impedance analog input (differential 5 MΩ |
| 4 | V- | power_in | Negative (lowest) power supply. Connect to GND for single-supply operation or to the negative rail for dual-supply operation. Total supply (V+ - V-) 2.7 V to 36 V; 36 V absolute maximum. |
| 5 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; not used by the die. |
| 6 | OUT | output | Op-amp output. Rail-to-rail-ish output that swings to within ~10 mV of the negative rail with light load. Short-circuit current ~7 mA sourcing / 10 mA sinking; output short-circuit-protected continuously. |
| 7 | V+ | power_in | Positive (highest) power supply. Total supply (V+ - V-) 2.7 V to 36 V; 36 V absolute maximum. Bypass with 0.1 µF close to the pin. |
| 8 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; not used by the die. |
