Op Amps Minimize Drift

The MAX9613 and MAX9615 rail-to-rail operational amplifiers employ self-calibration that automatically compensates for errors generated over time or by temperature. Each time the system is powered on, self-calibration activates, thereby minimizing system drift errors induced by temperature gradients. Both devices operate from a 1.8V to 5.5V supply and consume 220 µA of quiescent current. Other shared features include an offset voltage of 100 µV, input-bias current of 1.55 pA, and a voltage-noise density of 28 nV/√Hz. The MAX9613 includes a shutdown mode. Prices start at $0.65 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
