CBM8655AS8 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 connect; the datasheet marks this pin NC = NO CONNECT. |
| 2 | -IN | input | Inverting input of the rail-to-rail CMOS amplifier; input voltage range is 0 V to 5 V at VS = 5 V and must stay within VSS-0.3 V to VDD+0.3 V. |
| 3 | +IN | input | Non-inverting input of the rail-to-rail CMOS amplifier; input voltage range is 0 V to 5 V at VS = 5 V and must stay within VSS-0.3 V to VDD+0.3 V. |
| 4 | V- | power_in | Negative supply pin, which is ground in single-supply operation; the datasheet recommends a 0.1 µF bypass capacitor close to the package. |
| 5 | NC | unconnected | No connect; the datasheet marks this pin NC = NO CONNECT. |
| 6 | OUT | output | Rail-to-rail amplifier output with ±220 mA output current at VS = 5 V, indefinite short-circuit duration to GND and capacitive load drive up to 500 pF. |
| 7 | V+ | power_in | Positive supply pin for 2.7 V to 5.5 V operation with an absolute maximum supply voltage of 6 V, bypassed with 0.1 µF and 4.7 µF capacitors. |
| 8 | NC | unconnected | No connect; the datasheet marks this pin NC = NO CONNECT. |
