AD202KNATI

The AD202KNATI is a high voltage isolation amplifier module designed for applications where signals must be measured, processed, or transmitted without a direct galvanic connection between input and output.
Using an internal transformer-coupled architecture, it provides both signal isolation and isolated power, forming a complete isolated signal-conditioning solution in a compact 10-pin DIP package.

By integrating the isolation barrier and DC-DC power stage, the AD202KNATI eliminates the need for an external isolated power supply, simplifying system design and reducing overall component count and cost.
It offers high common-mode rejection, low drift, and wide bandwidth, making it well suited for high voltage measurement, industrial control, medical instrumentation, and other precision systems that operate in electrically noisy or high-potential environments.
