CBM8051NST6 from Corebai Microelectronics, in a SOT-23-6. 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, able to deliver at least 84 mA (130 mA typ) of output current. |
| 2 | VSS | power_in | Negative supply, or ground in single-supply operation. |
| 3 | IN+ | input | Non-inverting amplifier input, with a common-mode range of -0.2 V to +3.8 V typical. |
| 4 | IN- | input | Inverting amplifier input. |
| 5 | Disable | input | Power-down control input: below 0.8 V max disables the amplifier, above 2 V min enables it, and supply current in disable is reduced to about 75 µA. |
| 6 | VDD | power_in | Positive supply of 2.5 V to 5.5 V, bypassed with a 0.1 µF ceramic capacitor. |
