CN951 from ShangHai Consonance Elec, 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 | AMPOUT | output | Operational amplifier output (rail-to-rail); short-circuit duration to GND/VCC is continuous. |
| 2 | AMPIN- | input | Operational amplifier inverting input. |
| 3 | AMPIN+ | input | Operational amplifier non-inverting input. |
| 4 | GND | power_in | Ground. |
| 5 | COMPIN+ | input | Voltage comparator non-inverting input; thresholds are VREF+0.007V rising and VREF-0.007V falling (the inverting input is tied internally to REF). |
| 6 | REF | output | Reference voltage output, typically 1.211V ±2%, internally connected to the comparator inverting input; sources or sinks 20µA and should not have a capacitor above 100pF. |
| 7 | COMPOUT | output | Voltage comparator output (rail-to-rail); short-circuit duration is 2 seconds. |
| 8 | VCC | power_in | Positive supply, 2.5V to 5.5V operating (absolute maximum -0.3V to +6.5V). |
