The AD8027 rail-to-rail operational amplifier from Analog Devices offers a "selectable crossover" feature that minimizes distortion. Like other op amps with rail-to-rail inputs and outputs, this one features an input stage that switches from one differential pair to another as the input signal crosses the threshold voltage. Yet with the '8027, designers can select a threshold close to either the positive or negative supply rail. The company claims the industry's lowest distortion over the full input range, including the crossover glitch. Pricing is $1.19 each/1000. For more, go to www.analog.com/AD8027. Analog Devices Inc.
