Product Details
The AD8225 is an instrumentation amplifier with fixed gain of 5 that sets new standards of performance.The superior CMRR of the AD8225 enables rejection of high frequency common mode voltage (80 dB Min @10 kHz).As a result,higher ambient levels of noise from utility lines,industrial equipment and other radiating sources,are rejected. Extended CMV range enables the AD8225 to extract low-level differential signals in the presence of high common-mode dc voltage levels even at low supply voltages.

Tools & Simulations
In-Amp Diamond Plot Tool
The Diamond Plot Tool is a web application that generates a configuration-specific Output Voltage Range vs. Input Common-Mode Voltage graph, also known as the Diamond Plot, for Analog Devices Instrumentation Amplifiers. Based on user inputs such as supply voltage, gain, and input signal range, the tool detects saturation and recommends in-amps for which the input signal is in-range and the configuration is valid. Avoid saturation, find the best in-amp for your design, and save time.

Design Tools
In-Amp Error Calculator
These tools will help estimate error contributions in your instrumentation amplifier circuit. It uses input parameters such as temperature, gain, voltage input, and source impedance to determine the errors that can contribute to your overall design.
