OP2177ARZ

UMW · Precision OpAmps · SOP-8

OP2177ARZ from UMW, 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 OUT A output Amplifier A output, stable with capacitive loads over 1000 pF with no external compensation.
2 -IN A input Amplifier A inverting input, internally protected by 500 Ω series resistors allowing signals several volts beyond either supply without phase reversal.
3 +IN A input Amplifier A non-inverting input, internally protected by 500 Ω series resistors allowing signals several volts beyond either supply without phase reversal.
4 V- power_in Negative supply (dual-supply operation ±2.5 V to ±15 V, 36 V maximum total supply).
5 +IN B input Amplifier B non-inverting input, internally protected by 500 Ω series resistors allowing signals several volts beyond either supply without phase reversal.
6 -IN B input Amplifier B inverting input, internally protected by 500 Ω series resistors allowing signals several volts beyond either supply without phase reversal.
7 OUT B output Amplifier B output, stable with capacitive loads over 1000 pF with no external compensation.
8 V+ power_in Positive supply (dual-supply operation ±2.5 V to ±15 V, 36 V maximum total supply).

CAD (KiCad official)

  • Symbol: OP2177ARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: op2177arz-etched.step / op2177arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); op2177arz.step / op2177arz.glb are the bare package body.
