AD8027ART-REEL7 GENERAL DESCRIPTION

The AD8027/AD80281 are high speed amplifiers with rail-to-railinput and output that operate on low supply voltages and areoptimized for high performance and a wide dynamic signal range.The AD8027/AD8028 have low noise (4.3 nV/√Hz, 1.6 pA/√Hz)and low distortion (120 dBc at 1 MHz). In applications that use afraction of or use the entire input dynamic range and requirelow distortion, the AD8027/AD8028 are ideal choices.Many rail-to-rail input amplifiers have an input stage that switchesfrom one differential pair to another as the input signal crossesa threshold voltage, which causes distortion. The AD8027/AD8028have a unique feature that allows the user to select the inputcrossover threshold voltage through the DISABLE/SELECT pin(DISABLE/SELECT x in the 10-lead MSOP, hereafter referredto as DISABLE/SELECT throughout this data sheet). This featurecontrols the voltage at which the complementary transistorinput pairs switch. The AD8027/AD8028 also have intrinsicallylow crossover distortion.1 Protected by U.S. patent numbers 6,486,737B1; 6,518,842B1.
