AMC1301SDWVR

Overview

The AMC1301SDWVR is a precision reinforced isolated amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features a differential output and operates on a supply voltage ranging from 3 V to 5.5 V with a typical quiescent current of 5 mA. The device provides a fixed gain of 8.2 V/V and supports a bandwidth of 210 kHz at the -3 dB point. Key electrical specifications include a maximum input offset voltage of 50 µV, an input bias current of 60 µA, and a common-mode rejection ratio of 93 dB. It offers galvanic isolation rated at 5 kVrms and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced galvanic isolation between input and output circuits for high noise immunity
• Delivers precision amplification with low input offset voltage and high common-mode rejection
• Features a wide operating temperature range suitable for demanding industrial environments

Applications

• Current sensing in motor drives and power converters
• Isolated signal conditioning for data acquisition systems
• Industrial process control loop monitoring

Procurement Notes

Verify the specific suffix 'DWVR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SOIC footprint matches the design board layout constraints. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a single-channel isolated amplifier with a fixed gain of 8.2 V/V is required. It is appropriate for applications needing ±250 mV input range handling and high-speed response up to 210 kHz. Consider the 5 kVrms isolation rating for safety-critical interfaces where ground loops must be eliminated.

Part Context

This part belongs to the AMC1301 family of precision isolated amplifiers from Texas Instruments. The family includes variants such as the AMC1301DWVR and AMC1301SDWVRG4, which share core performance characteristics but may differ in packaging or regulatory compliance markings. These devices are designed to replace traditional transformer-based isolation solutions in modern electronic designs.

Replacement Considerations

AMC1301DWVR serves as a direct functional substitute within the same series.
