AMC1100DWVR

Overview

The AMC1100DWVR is a precision isolated amplifier manufactured by Texas Instruments, housed in an 8-pin SOIC package. It features a ±250-mV differential input and a fully differential output, providing galvanic isolation via a silicon dioxide barrier. Key electrical parameters include a 4.25 kVrms insulation voltage, a 100 kHz 3dB bandwidth, and a common-mode rejection ratio of 108 dB. The device operates on supply voltages ranging from 2.7 V to 5.5 V with low power consumption. It exhibits a gain error of 0.075% and an input offset voltage of 200 µV, ensuring high accuracy for measurement applications.

Feature Summary

• Provides galvanic isolation between input and output circuits using a robust silicon dioxide barrier.
• Features a fully differential output architecture to enhance noise immunity and signal integrity.
• Delivers high-precision measurement capabilities with low gain error and minimal input offset voltage.

Applications

• Isolated current and voltage measurement in industrial systems
• Analog front-end design for motor control applications
• Power monitoring and energy metering equipment

Procurement Notes

Verify the specific suffix 'DWVR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards as indicated in official manufacturer documentation. Ensure compatibility with the intended operating temperature range of -40°C to +105°C for the target application environment before finalizing procurement.

Selection Notes

Select this component when a single-channel isolated amplifier with a ±250-mV input range is required. It is suitable for designs needing high common-mode rejection and low power consumption within a small SOIC footprint. Consider alternative packages like DUBR if a smaller WSON form factor is preferred for space-constrained layouts.

Part Context

This part belongs to the AMC1100 family of precision isolated amplifiers from Texas Instruments. These devices are designed to replace traditional optocoupler-based solutions, offering superior linearity and bandwidth. The family includes variants such as the AMC1200 and different package options to support diverse industrial and automotive measurement requirements.

Replacement Considerations

The AMC1100DUBR serves as a pin-compatible alternative in a smaller WSON package. Verify functional equivalence regarding input range and isolation ratings when substituting other models within the same product family.
