ShangHai Consonance Elec · Comparators · SOP-8

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).

CAD (KiCad official)

  • Symbol: CN951
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cn951-etched.step / cn951-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cn951.step / cn951.glb are the bare package body.
