HX432-S from ZHHXDZ, in a SOP-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 | AOUT | output | Output of op amp A, which has a sink current capability of 0.2mA to 10mA in the reference application. |
| 2 | AIN- | input | Inverting input of op amp A. |
| 3 | AIN+ (VZ) | input | Non-inverting input of op amp A, tied internally to the 2.5V shunt reference (VZ 2.450V to 2.550V, minimum cathode current 150µA typ/200µA max for regulation). |
| 4 | GND | power_in | Ground; all voltages are measured with respect to GND = 0V. |
| 5 | BIN+ | input | Non-inverting input of op amp B, with common-mode input range of 0V to VS-1V. |
| 6 | BIN- | input | Inverting input of op amp B. |
| 7 | BOUT | output | Output of op amp B, with typical source current 30mA and sink current 11mA. |
| 8 | VS | power_in | Positive supply, 2.5V to 16V operating (minimum is for amplifier B only) and 20V absolute maximum. |
