**Texas Instruments** · Operational Amplifier · VSSOP-8

LMV552MMX 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 | OUT A | output | Output of amplifier channel A with output swing of 40-48mV from positive rail into 100kΩ load at 25°C |
| 2 | -IN A | input | Inverting input of amplifier channel A with common-mode voltage range from 0V to 2.1V at 3V supply or 0V to 4.1V at 5V supply |
| 3 | +IN A | input | Non-inverting input of amplifier channel A with common-mode voltage range from 0V to 2.1V at 3V supply or 0V to 4.1V at 5V supply |
| 4 | V- | power_in | Negative power supply return with recommended supply voltage range of 2.7V to 5.5V relative to V+ |
| 5 | +IN B | input | Non-inverting input of amplifier channel B with common-mode voltage range from 0V to 2.1V at 3V supply or 0V to 4.1V at 5V supply |
| 6 | -IN B | input | Inverting input of amplifier channel B with common-mode voltage range from 0V to 2.1V at 3V supply or 0V to 4.1V at 5V supply |
| 7 | OUT B | output | Output of amplifier channel B with output swing of 40-48mV from positive rail into 100kΩ load at 25°C |
| 8 | V+ | power_in | Positive power supply with recommended supply voltage range of 2.7V to 5.5V above V- |
