# OPA837IDCKT

**Texas Instruments** · Operational Amplifier · SC-70-5

OPA837IDCKT from Texas Instruments, in a SC-70-5. 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 | Amplifier output; the output is rail-to-rail, swinging to within about 100 mV of the supply rails. |
| 2 | VS- | power_in | Negative power-supply pin; the absolute maximum supply voltage (VS- to VS+) is 5.5 V. |
| 3 | VIN+ | power_in | Noninverting input pin; linear input common-mode operation is ensured down to the negative supply and to within 1.3 V of the positive supply at 25°C. |
| 4 | VIN- | power_in | Inverting input pin; input voltage must stay within VS- - 0.5 V to VS+ + 0.5 V (absolute maximum). |
| 5 | VS+ | power_in | Positive power-supply input; recommended single-supply voltage is 2.7 V to 5.4 V (5 V nominal). |
