HT8628ARTZ from HTCSEMI, in a SOT23-5. 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 | output | Amplifier output with rail-to-rail swing (VOH 4.98V typ at VS=5V, RL=10kΩ), sourcing 82mA and sinking 84mA typical. |
| 2 | -Vs | power_in | Negative supply (ground in single-supply operation); the supply range from +Vs is 2.2V to 5.5V. |
| 3 | +In | input | Non-inverting input with rail-to-rail common-mode range (-0.1V to +5.6V at VS=5.5V) and 100pA typical input bias current. |
| 4 | -In | input | Inverting input with rail-to-rail common-mode range and 100pA typical input bias current. |
| 5 | +Vs | power_in | Positive supply, 2.2V to 5.5V (absolute maximum 7.5V between supplies); bypass with a 0.1µF ceramic capacitor close to the pin. |
