600 kHz gain-bandwidth — where the signal chain stays clean
The OP177FSZ-REEL7 is a single-channel general-purpose op-amp with a 600 kHz gain-bandwidth product. For a non-inverting stage with a gain of 10, that bandwidth collapses to about 60 kHz — enough for audio, sensor conditioning, and slow control loops, but not for video or high-speed data acquisition. Slew rate is 0.3 V/µs, which means the output can swing 3 V in 10 µs. That limits the full-power bandwidth to roughly 10 kHz at a 10 V peak-to-peak swing — fine for DC-coupled signals and low-frequency AC, but the output will slew-limit on a 20 kHz square wave.
10 µV offset — the DC precision that saves the trim pot
Input offset voltage is 10 µV typical, with 1.2 nA input bias current. That combination means a non-inverting stage with a 10 kΩ source resistor sees less than 12 µV of offset from bias current alone — the offset voltage dominates. No external nulling pot needed for most 12-bit or even 14-bit systems. Supply range spans 6 V to 36 V single or dual supply (±3 V to ±18 V). The 1.6 mA quiescent current per amplifier is moderate — not a micropower part, but not a power hog either. Good fit for industrial control boards where a single 24 V rail powers the analog front-end.
Active lifecycle — no last-time-buy scramble
Operating temperature range is -40°C to 85°C, which covers industrial enclosures and outdoor telecom cabinets. The 8-SOIC package with 0.154-inch body width is a standard footprint — same land pattern as the AD8622, AD623, and dozens of other single op-amps.
