It offers a gain-bandwidth product of 600 kHz and a slew rate of 0.3 V/µs, which together define its useful bandwidth for low-frequency amplification — think thermocouple or strain-gauge front-ends, not video or switching regulators. The input offset voltage is trimmed to 20 µV, and input bias current sits at 1.2 nA, so the part handles DC accuracy without external nulling in most designs. Supply range spans 6 V to 36 V single or dual supply, and the operating temperature covers -40°C to 85°C, making it suitable for industrial control cabinets and outdoor telecom enclosures.
The OP177GSZ-REEL comes in an 8-SOIC package (0.154" body width, 3.90 mm) and is specified for surface-mount assembly. The footprint matches the standard SOIC-8 land pattern — no special pad geometry needed. If you are hand-prototyping, the Cut Tape option gives you a few parts without committing to a full reel.
The 600 kHz gain-bandwidth product sets the frequency where the open-loop gain drops to unity.
