# 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.
