AD202KNATI

Overview

The AD202KNATI is a high voltage isolation amplifier module from Analog Technologies, Inc. It features an isolated power output and operates with 15V DC supply. The device provides a common mode rejection ratio (CMR) of 130dB at a gain of 100V/V. It has a bandwidth of 800kHz and supports ±2000V common mode voltage (CMV). Designed as a drop-in replacement for legacy models, it utilizes transformer coupling for signal isolation in industrial environments.

Feature Summary

• High common mode rejection ratio of 130dB
• Transformer-coupled isolation architecture
• Integrated isolated power outputs
• Compact physical footprint

Applications

• Data acquisition systems
• Motor control circuits
• Current shunt measurement
• Process signal isolation

Procurement Notes

Verify the specific suffix KNATI against your bill of materials to ensure compatibility with existing PCB footprints and pin configurations. Confirm that the 15V DC operating requirement aligns with your system power design. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing procurement.

Selection Notes

Select this component when high voltage isolation is required between input and output stages. It serves as a direct upgrade for older AD202 variants. Ensure the application demands the specified 800kHz bandwidth and 130dB CMR. Consider the small size constraint if space is limited within the enclosure.

Part Context

This part belongs to the AD202 series of high voltage isolation amplifiers manufactured by Analog Technologies, Inc. The series is designed for robust performance in noisy industrial environments. The AD202KNATI specifically represents an upgraded version intended to replace previous iterations while maintaining pin compatibility.

Replacement Considerations

Officially documented as an upgraded drop-in replacement for the AD202KN. Verify pin-to-pin compatibility with legacy designs before substitution.
