CBM8333AS8 from Corebai Microelectronics, 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 connection. |
| 2 | INA- | input | Inverting input of the amplifier; keep within VSS-0.1V to VDD+0.1V (rail-to-rail input), absolute max VSS-0.5V to VDD+0.5V. |
| 3 | INA+ | input | Non-inverting input of the amplifier; keep within VSS-0.1V to VDD+0.1V (rail-to-rail input), absolute max VSS-0.5V to VDD+0.5V. |
| 4 | VSS | power_in | Negative supply or ground; single supply 1.8V to 5.5V, or dual supply ±0.9V to ±2.75V. |
| 5 | NC | unconnected | No connection. |
| 6 | OUT | output | Rail-to-rail amplifier output, with typical short-circuit current of 20mA and output current of 30mA. |
| 7 | VDD | power_in | Positive supply, 1.8V to 5.5V (absolute max 7.5V between VDD and VSS), bypass with a 0.1µF ceramic capacitor. |
| 8 | NC | unconnected | No connection. |
