# OPA827AIDGKT

**Texas Instruments** · FET Input Amplifiers · MSOP-8

OPA827AIDGKT from Texas Instruments, in a MSOP-8. 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 | NC | unconnected | No internal connection; the datasheet states it can be left floating. |
| 2 | -IN | input | Inverting input; input voltage must stay within (V-) - 0.5 V to (V+) + 0.5 V and input current is limited to ±10 mA absolute maximum. |
| 3 | +IN | input | Noninverting input; input voltage must stay within (V-) - 0.5 V to (V+) + 0.5 V and input current is limited to ±10 mA absolute maximum. |
| 4 | V- | power_in | Negative power supply; recommended supply range is ±4 V to ±18 V. |
| 5 | NC | unconnected | No internal connection; the datasheet states it can be left floating. |
| 6 | OUT | output | Amplifier output; the datasheet specifies continuous short-circuit protection (short-circuit to VS/2). |
| 7 | V+ | power_in | Positive power supply; recommended supply range is ±4 V to ±18 V. |
| 8 | NC | unconnected | No internal connection; the datasheet states it can be left floating. |
