Zero Drift Amps Take Low-Power Trip

Using auto-zeroing techniques to provide low offset voltage and near-zero drift over time/temperature, the OPA333 op amps specify an offset of 2 mV, quiescent current of 17 mA, and operating voltages down to 1.8V. They offer high-impedance inputs with a common-mode range of 100 mV beyond both rails and rail-to-rail outputs within 100 mV of the rail. Single or dual supplies from 1.8V to 5.5V can be used. Available in SC70, SOT23-5, and SO-8, pricing is $0.95 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
