# LMV791MK

**Texas Instruments** · Operational Amplifier · TSOT-23-6

LMV791MK from Texas Instruments, in a TSOT-23-6. 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 | Out | output | Amplifier output with rail-to-rail swing that can drive 600 Ω loads with source current up to 60 mA. |
| 2 | V- | power_in | Negative (lowest) supply voltage pin; with single-supply operation this is the ground reference, and the common-mode range includes the negative rail. |
| 3 | +IN | input | Non-inverting input of the CMOS input stage, with a common-mode voltage range that extends down to ground (−0.3 V to 1.5 V at 2.5 V supply, −0.3 V to 4 V at 5 V supply, CMRR ≥ 60 dB at 25°C). |
| 4 | -IN | input | Inverting input of the CMOS input stage, with typical input bias current of about 0.1 pA at 5 V and 25°C. |
| 5 | EN | input | Enable input: drive above V+ − 0.5 V to power the amplifier on and below V− + 0.5 V to shut it down, reducing supply current below 1 µA. |
| 6 | V+ | power_in | Positive (highest) supply voltage pin; operating supply range is 1.8 V to 5.5 V, with absolute maximum V+ − V− of 6 V. |
