Overview
The AD8028ARZ is a high-performance, low distortion, high-speed operational amplifier produced by Analog Devices Inc. This amplifier is characterized by its rail-to-rail input and output capabilities, operating on low supply voltages ranging from 2.7 V to 12 V. It is optimized for applications requiring high speed and low distortion, making it suitable for a wide dynamic signal range. The AD8028ARZ features a unique input crossover threshold selection via the DISABLE/SELECT pin, which helps in controlling the voltage at which the complementary transistor input pairs switch, thereby reducing crossover distortion.
