ADA4432-1WBCPZ-R7 from Analog Devices, in a LFCSP-WD-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 | NC | unconnected | No connect; do not connect to this pin. |
| 2 | STB | output | Short-to-battery indicator output; logic high indicates a short-to-battery condition and logic low indicates normal operation. |
| 3 | +VS | power_in | Positive power supply (2.6 V to 3.6 V operating range); bypass with a 0.1 µF capacitor to GND. |
| 4 | OUT | output | Amplifier output, protected against short-to-battery overvoltage up to 18 V and short to ground. |
| 5 | NC | unconnected | No connect; do not connect to this pin. |
| 6 | GND | power_in | Power supply ground pin. |
| 7 | ENA | input | Enable function; connect to +VS or float for normal operation, connect to GND to disable the device (internally pulled up to +VS through 250 kΩ). |
| 8 | IN | input | Amplifier input; input voltage range is typically 0 to 1.4 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `ADA4432-1WBCPZ-R7`
- Footprint: `Package_CSP:LFCSP-WD-8-1EP_3x3mm_P0.65mm_EP1.6x2.44mm`
- 3D model: LFCSP-WD-8, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.35 mm nominal DSBGA height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `ada4432-1wbcpz-r7-etched.step` / `ada4432-1wbcpz-r7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ada4432-1wbcpz-r7.step` / `ada4432-1wbcpz-r7.glb` are the bare package body.
