# LPV542DNXR

**Texas Instruments** · Operational Amplifier · SON-8-EP(3x3)

LPV542DNXR from Texas Instruments, in a SON-8-EP(3x3). 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 | Channel A output of the dual op amp. |
| 2 | -IN A | input | Channel A inverting input; input pins are diode-clamped to the supply rails, and signals more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 3 | +IN A | input | Channel A non-inverting input; input pins are diode-clamped to the supply rails, and signals more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 4 | V- | power_in | Negative (lowest) power supply; recommended operating supply voltage V+ to V- is 1.6 V to 5.5 V. |
| 5 | +IN B | input | Channel B non-inverting input; input pins are diode-clamped to the supply rails, and signals more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 6 | -IN B | input | Channel B inverting input; input pins are diode-clamped to the supply rails, and signals more than 0.3 V beyond the rails should be current-limited to 10 mA or less. |
| 7 | OUT B | output | Channel B output of the dual op amp. |
| 8 | V+ | power_in | Positive (highest) power supply; recommended operating supply voltage V+ to V- is 1.6 V to 5.5 V. |
| 9 | DAP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `LPV542DNXR`
- Footprint: `Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm`
- 3D model: SON-8-EP(3x3) (KiCad packages3D, STEP)
- 3D model files: `lpv542dnxr-etched.step` / `lpv542dnxr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lpv542dnxr.step` / `lpv542dnxr.glb` are the bare package body.
