Low distortion amp has 'selectable threshold'

26 February 2003 Analogue, Mixed Signal, LSI Commercial (Industry)

A new family of high-performance amplifiers with rail-to-rail inputs and outputs that work on supply voltages down to 2,7 V has been announced by Analog Devices. The first device, the AD8027 features high bandwidth (180 MHz, G = +1), and 100 V/µs slew rate. Low distortion over the entire input range is the most unique feature. While all amplifiers with rail-to-rail inputs have an input stage that switches from one differential pair to another as the input signal crosses the threshold voltage, the AD8027 has a unique 'selectable crossover' feature that allows that threshold to be selected - close to either the positive or negative rail - at the designer's discretion, minimising the effects of crossover distortion. The AD8027 offers very low distortion over the entire input range, including the crossover glitch. It has low quiescent current (6 mA max), and a power down feature. It is designed to work where speed, performance and dynamic range are critical. The AD8027 comes in SOT-23 and SOIC packages and is rated for -40 to +85°C.
