First Monolithic FET Op Amp with 1 µV/°C Drift

AD547 Is Laser-Trimmed on the Wafer for Both Offset and Drift; 25pA Warmed-Up Bias Current Is Lower than for Any BIFET Op Amp

The AD547 is a monolithic FET-input operational amplifier that combines in one low-cost device the low bias current inherent in FET circuitry, the low offset voltage and drift that are more typical of bipolar circuitry, high open-loop gain—for accurate performance in high-closed-loop-gain circuits—and smooth dynamic performance with low distortion.
