AD8138ARZ General Description

The AD8138ARZ is a high-speed, low-power voltage feedback amplifier designed for use in applications requiring wide bandwidth and high slew rate. It offers a gain bandwidth product of 250MHz and a slew rate of 1200V/µs, making it suitable for amplifying high-frequency signals with minimal distortion. This amplifier operates on a single 5V to 12V power supply and consumes only 5.5mA of supply current, making it ideal for low-power applications. It features a differential input that allows for easy interfacing with differential signal sources, such as those found in communication systems and instrumentation equipment. The AD8138ARZ also offers excellent common-mode rejection ratio (CMRR) and high input impedance, ensuring accurate signal processing in the presence of common-mode noise. Its adjustable gain allows for flexibility in signal conditioning, and its small footprint makes it suitable for use in space-constrained designs.
