# LPV321M5

**Texas Instruments** · Operational Amplifier · SOT-23-5

LPV321M5 from Texas Instruments, in a SOT-23-5. 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 | +IN | input | Noninverting input of the amplifier; the input common-mode voltage range includes ground (VCM from -0.2 V to V+ - 0.8 V). |
| 2 | V- | power_in | Negative (lowest) power supply; the device is specified for supply voltage 2.7 V to 5 V and the absolute maximum supply voltage (V+ - V-) is 5.5 V. |
| 3 | -IN | input | Inverting input of the amplifier. |
| 4 | OUTPUT | output | Amplifier output with rail-to-rail swing; shorting the output to V+ or V- will adversely affect reliability. |
| 5 | V+ | power_in | Positive (highest) power supply; the device is specified for supply voltage 2.7 V to 5 V and the absolute maximum supply voltage (V+ - V-) is 5.5 V. |
