High-precision, single-function operational amplifier featuring a chopper-stabilized architecture for ultra-low input offset voltage (10µV max). This industrial-grade IC operates across a wide temperature range (-40°C to 85°C) with a nominal supply voltage of ±15V, supporting limits up to ±18V. Delivering a minimum voltage gain of 1,000,000 and a nominal unity-gain bandwidth of 500kHz, it offers a nominal slew rate of 0.5V/µs and a high common-mode reject ratio of 140. Packaged in a 14-pin PDIP (R-PDIP-T14), this amplifier is designed for demanding applications requiring exceptional accuracy and stability.
