AD8475ACPZ-R7 from Analog Devices, in a LFCSP-16(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 | +IN 0.4x | input | Positive input for 0.4 attenuation; the 0.4 gain is selected by driving the input pin corresponding to that gain. |
| 2 | +IN 0.8x | input | Positive input for 0.8 attenuation; the 0.8 gain is selected by driving the input pin corresponding to that gain. |
| 3 | −IN 0.8x | input | Negative input for 0.8 attenuation; the 0.8 gain is selected by driving the input pin corresponding to that gain. |
| 4 | −IN 0.4x | input | Negative input for 0.4 attenuation; the 0.4 gain is selected by driving the input pin corresponding to that gain. |
| 5 | −IN 0.4x | input | Negative input for 0.4 attenuation; the 0.4 gain is selected by driving the input pin corresponding to that gain. |
| 6 | +VS | power_in | Positive supply; single supply 3 V to 10 V or dual supplies ±1.5 V to ±5 V per the Features list. |
| 7 | +VS | power_in | Positive supply; single supply 3 V to 10 V or dual supplies ±1.5 V to ±5 V per the Features list. |
| 8 | +VS | power_in | Positive supply; single supply 3 V to 10 V or dual supplies ±1.5 V to ±5 V per the Features list. |
| 9 | VOCM | input | Output common-mode adjust; sets the output common-mode voltage, with an input voltage range of −VS + 1 V to +VS per the specifications. |
| 10 | +OUT | output | Positive output of the fully differential amplifier. |
| 11 | −OUT | output | Negative output of the fully differential amplifier. |
| 12 | NC | unconnected | No connect. |
| 13 | −VS | power_in | Negative supply. |
| 14 | −VS | power_in | Negative supply. |
| 15 | −VS | power_in | Negative supply. |
| 16 | +IN 0.4x | input | Positive input for 0.4 attenuation; the 0.4 gain is selected by driving the input pin corresponding to that gain. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
