Overview

The AD8250ARMZ is a high-speed, digitally programmable gain instrumentation amplifier (PGIA) that offers gain settings of 1, 2, 5, and 10. It features a high bandwidth of 10 MHz and a fast slew rate of 20V/us, making it suitable for high-speed data acquisition systems. The part is designed to maintain high common-mode rejection even at high frequencies, which is critical for extracting small signals in noisy environments.

Why Choose This Part

The AD8250ARMZ provides excellent dynamic performance with a 20V/us slew rate and 10 MHz bandwidth, which is significantly higher than many standard instrumentation amplifiers. Its digital gain control eliminates the need for external precision resistors, reducing board space and improving gain accuracy over temperature.

Applications

Data Acquisition Systems
Used as a front-end amplifier for high-speed ADCs to provide variable gain and high input impedance.
Industrial Process Control
Ideal for amplifying low-level signals from industrial sensors while rejecting common-mode noise.
Automatic Test Equipment
The programmable gain feature allows for dynamic range adjustment during automated testing cycles.
Bioelectric Signal Amplification
Supports medical instrumentation requiring high CMRR and low input bias current for precision measurements.

Getting Started

Engineers can evaluate this part using the AD8250-EVALZ evaluation board. The gain is set via digital pins, which can be driven directly by a microcontroller GPIO or hard-wired for fixed-gain applications. Ensure proper decoupling with 0.1uF and 10uF capacitors on the supply pins to maintain high-speed stability.
