63 MHz GBW, 17 V/µs — the speed-offset trade-off
The OP37GSZ-REEL7 is a single-channel precision op-amp from Analog Devices with a 63 MHz gain-bandwidth product and a 17 V/µs slew rate, making it one of the faster precision amplifiers in the standard SOIC-8 footprint. The 30 µV input offset voltage keeps DC errors low enough for 12- to 14-bit signal chains without external trimming.
Supply rails and temperature grade
Operates from a single 8 V to 36 V supply or a split ±4 V to ±18 V supply, covering common industrial rails (12 V, 24 V, ±15 V). The -40°C to 85°C temperature range suits factory-floor and outdoor-enclosure environments — the part is not qualified for extended automotive (125°C) operation. The 15 nA input bias current is moderate — for a 10 kΩ source impedance the DC error from bias is 150 µV, comparable to the offset itself. For high-impedance sources above 1 MΩ, a FET-input op-amp would be a better fit.
Package and sourcing posture
Housed in an 8-SOIC narrow-body package (3.90 mm width), the OP37GSZ-REEL7 uses the standard SOIC-8 footprint. The REEL7 suffix indicates Tape & Reel packaging — 2,500 pieces per reel — with Cut Tape available for smaller quantities. Active lifecycle status per Analog Devices; ROHS3 compliant with no lead or restricted-substance exemptions. Sourced to order against BOM quantities through independent distribution.
