# OPA727AIDGKR

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

OPA727AIDGKR 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; leave unconnected (datasheet note 1 on the pin configuration). |
| 2 | -IN | input | Inverting input; the input common-mode range extends from V- to (V+) - 2.5V, and inputs beyond the supply rails by more than about 300mV should be current limited to 10mA. |
| 3 | +IN | input | Non-inverting input; the input common-mode range extends from V- to (V+) - 2.5V, and inputs beyond the supply rails by more than about 300mV should be current limited to 10mA. |
| 4 | V- | power_in | Negative power supply rail, the reference for the input common-mode range and the output swing. |
| 5 | NC | unconnected | No internal connection; leave unconnected (datasheet note 1 on the pin configuration). |
| 6 | OUT | output | Amplifier output, rail-to-rail class AB stage that swings to within 150mV of the rails at light loads (>100kΩ) and within 250mV with a 1kΩ load. |
| 7 | V+ | power_in | Positive power supply; the part is specified for 4V to 12V single supply (or ±2V to ±6V dual supply), with an absolute maximum supply of 13.2V. |
| 8 | NC | unconnected | No internal connection; leave unconnected (datasheet note 1 on the pin configuration). |

## CAD (KiCad official)

- Symbol: `OPA727AIDGKR`
- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`
- 3D model: VSSOP-8 (KiCad packages3D, STEP)
- 3D model files: `opa727aidgkr-etched.step` / `opa727aidgkr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa727aidgkr.step` / `opa727aidgkr.glb` are the bare package body.
