The AD8027/AD8028 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.With their wide supply voltage range (2.7 V to 12 V) and widebandwidth (190 MHz), the AD8027/AD8028 amplifiers aredesigned to work in a variety of applications where speed andperformance are needed on low supply voltages. The high performanceof the AD8027/AD8028 is achieved with a quiescentcurrent of only 6.5 mA (typical) per amplifier. The AD8027/AD8028 have a shutdown mode that is controlled viathe DISABLE/SELECT pin.The AD8027/AD8028 are available in 8-lead SOIC, 6-lead SOT-23,and 10-lead MSOP packages. The AD8028WARMZ-R7 is anautomotive grade version, qualified for automotive applications.See the Automotive Products section for more details. TheAD8027/AD8028 family is designed to work over the extendedtemperature range of −40°C to +125°C.Applications Filters ADC drivers Level shifting Buffering Professional video Low voltage instrumentation
