# LMV791MKX

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

LMV791MKX 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; the total supply V+ - V- is specified at 1.8 V to 5.5 V and the absolute maximum is 6 V. |
| 3 | +IN | input | Non-inverting input; the common-mode range includes the negative supply rail, so ground sensing is possible in single-supply operation. |
| 4 | -IN | input | Inverting input of the amplifier. |
| 5 | EN | input | Enable pin: the amplifier powers on when EN is above V+ - 0.5 V and shuts down when EN is below V- + 0.5 V (shutdown supply current is 1 µA or less). |
| 6 | V+ | power_in | Positive (highest) supply voltage; recommended operating range is 1.8 V to 5.5 V and the absolute maximum V+ - V- is 6 V. |
