# OPA197IDGKR

**Texas Instruments** · Precision Op Amps · VSSOP-8

OPA197IDGKR from Texas Instruments, in a VSSOP-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; can be left floating. |
| 2 | -IN | input | Inverting input; signal input pins are limited to a common-mode range of (V-) - 0.5 V to (V+) + 0.5 V and a current of ±10 mA. |
| 3 | +IN | input | Noninverting input; signal input pins are limited to a common-mode range of (V-) - 0.5 V to (V+) + 0.5 V and a current of ±10 mA. |
| 4 | V- | power_in | Negative (lowest) power supply; recommended operation is ±2.25 V to ±18 V dual supply or 4.5 V to 36 V single supply. |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | OUT | output | Amplifier output; output short circuit to ground is rated continuous (one amplifier per package). |
| 7 | V+ | power_in | Positive (highest) power supply; absolute maximum single-supply voltage is 40 V and recommended single-supply range is 4.5 V to 36 V. |
| 8 | NC | unconnected | No internal connection; can be left floating. |
