HT8358VRMZ from HTCSEMI, in a MSOP-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 | Channel A output, rail-to-rail; output current is specified at ±50 mA with VS = 5 V. |
| 2 | -IN A | input | Channel A inverting input; input voltage must stay between GND and VS (absolute maximum rating). |
| 3 | +IN A | input | Channel A non-inverting input; input common-mode range is 0 V to VS, with input voltage limited to GND to VS (absolute maximum). |
| 4 | V- | power_in | Negative supply rail (GND for single-supply operation); supply is 2.7 V to 5.5 V single supply, 6 V absolute maximum. |
| 5 | +IN B | input | Channel B non-inverting input; input common-mode range is 0 V to VS, with input voltage limited to GND to VS (absolute maximum). |
| 6 | -IN B | input | Channel B inverting input; input voltage must stay between GND and VS (absolute maximum rating). |
| 7 | OUT B | output | Channel B output, rail-to-rail; output current is specified at ±50 mA with VS = 5 V. |
| 8 | V+ | power_in | Positive supply rail; operates from 2.7 V to 5.5 V single supply, 6 V absolute maximum. |
