AD8028WARMZ-R7

AD8028WARMZ-R7 is a low-distortion, high-speed, rail-to-rail input/output amplifier. It operates on low supply voltages and is optimized for high performance and a wide dynamic signal range. 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. This feature controls the voltage at which the complementary transistor input pairs switch. It also has intrinsically low crossover distortion. The high performance of the device is achieved with a quiescent current of only 6.5mA (typical) per amplifier. It is used in applications such as filters, ADC drivers, level shifting, buffering, professional video, and low-voltage instrumentation.
