OP177GP

OP177GP is an 8-pin Plastic DIP precision operational amplifier from Analog Devices (Burr-Brown). It belongs to the OP177 family, known for very low input offset and drift, low input bias current, and low-noise performance, making it suitable for instrumentation, sensor conditioning, and precision buffering in data-acquisition circuits. The GP suffix indicates the package variant (Plastic DIP, Pb-free/green).
Typical features include high open-loop gain, low offset voltage (microvolt range), low offset drift, and modest bandwidth appropriate for precision signal amplification; it also offers good power-supply rejection and stable operation with standard feedback configurations. It generally requires a dual supply or a suitable single-supply within its rated range and is not rail-to-rail on inputs or outputs.
Applications include instrumentation amplifiers, transimpedance amplifiers, DAC/ADC front ends, and precision buffers. For exact electrical specs (offset, noise, GBW, supply range, pinout) and current availability, consult the latest Analog Devices datasheet for the OP177GP.

OP177GP is an 8-pin plastic DIP (DIP-8) package.

OP177GP is an 8-pin general-purpose precision operational amplifier (DIP-8 package). Pinout (typical):
- 1: Offset Null
- 2: Inverting Input (-)
- 3: Non-Inverting Input (+)
- 4: V−
- 5: Offset Null
- 6: Output
- 7: V+
- 8: Not Connected
It provides high-precision, low-offset amplification with offset-null capability.

Direct equivalents:
- TI OPA177 family (e.g., OPA177, OPA177A, OPA177AID) – drop-in cross for OP177GP.
- Analog Devices OP177 – the same device with different branding/packaging.
In short, OP177GP is the same precision op-amp as TI’s OPA177; GP just denotes the packaging.
