HT8631BRTZ from HTCSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INP | input | Non-inverting input of amplifier. Input voltage range is 0 V to VDD (rail-to-rail input). |
| 2 | GND | power_in | Ground pin. Connect to the most negative supply; all GND pads are connected on die. |
| 3 | INN | input | Inverting input of amplifier. Has the same 0 V to VDD input voltage range as INP. |
| 4 | OUT | output | Amplifier output. Rail-to-rail: swings to within ~10 mV of each supply rail into a light load. Short-circuit current ~80 mA. |
| 5 | VDD | power_in | Positive power supply. Operating range 2.5 V to 5.5 V (absolute max 6 V). Bypass locally with a ceramic capacitor to GND. |
