AMC1100DWV

Overview

The AMC1100DWVRG4 is a precision current-sense amplifier featuring an optically isolated architecture with a silicon dioxide barrier. It provides a fixed gain of 8 and supports a ±250-mV input range, optimized for shunt resistor measurements. The device offers high common-mode rejection and operates within a -40°C to +105°C temperature range. It utilizes a wide-body SOIC-8 (DWV) package and requires a 4.5-V to 5.5-V supply on the high side.

Feature Summary

• Optical isolation via silicon dioxide barrier for magnetic interference immunity
• Fixed gain configuration optimized for precise current sensing applications
• High common-mode rejection ratio for accurate measurement in noisy environments

Applications

• Industrial motor drives
• Power metering systems
• Voltage and current measurement front-ends

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required thermal performance for the intended operating environment.

Selection Notes

Select this component for designs requiring galvanic isolation between high-voltage sensing nodes and low-voltage control circuits. The fixed gain simplifies signal conditioning by eliminating external feedback components. Verify that the input voltage range aligns with the expected shunt drop.

Part Context

This part belongs to the AMC1100 family of isolation amplifiers from Texas Instruments. It shares functional similarities with the AMC1200 but differs in input configuration and gain settings. The DWV package denotes a wide-body SOIC format suitable for higher isolation creepage distances.

Replacement Considerations

AMC1200 serves as a fully-differential alternative within the same product family.
