HX8551AIDRG from HANSCHIP semiconductor, 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 | NC | unconnected | No connect pin on the HX8551A SOP-8 package. |
| 2 | INA- | input | Inverting input of the amplifier, with input range limited to VSS-0.1V to VDD+0.1V for normal operation. |
| 3 | INA+ | input | Non-inverting input of the amplifier, with input range limited to VSS-0.1V to VDD+0.1V for normal operation. |
| 4 | VSS | power_in | Negative supply or ground; for dual supply operation (±0.9V to ±2.75V) bypass with a 0.1µF ceramic capacitor. |
| 5 | NC | unconnected | No connect pin on the HX8551A SOP-8 package. |
| 6 | OUT | output | Rail-to-rail amplifier output. |
| 7 | VDD | power_in | Positive supply, 1.8V to 5.5V single supply (absolute maximum 7.5V), with a 0.1µF ceramic bypass capacitor placed close to the pin. |
| 8 | NC | unconnected | No connect pin on the HX8551A SOP-8 package. |
