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 a fraction of or use the entire input dynamic range and require low distortion, the AD8027/AD8028 are ideal choices. Many rail-to-rail input amplifiers have an input stage that switches from one differential pair to another as the input signal crosses a threshold voltage, which causes distortion. The AD8027/AD8028 have a unique feature that allows the user to select the input crossover threshold voltage through the DISABLE/SELECT pin (DISABLE/SELECT x in the 10-lead MSOP, hereafter referred to as DISABLE/SELECT throughout this data sheet). This feature controls the voltage at which the plementary transistor input pairs switch. The AD8027/AD8028 also have intrinsically low crossover distortion. With...
