AMC1350DWVR

Overview

The AMC1350DWVR is a precision, reinforced isolated amplifier featuring a ±5-V linear input voltage range and a fixed gain of 0.4 V/V. It provides galvanic isolation certified to 5000 VRMS per UL1577 and supports a working voltage up to 1.5 kVRMS. The device operates on 3.3 V or 5 V supplies with a maximum supply voltage of 5.5 V. Key electrical characteristics include a high common-mode transient immunity of 100 kV/μs, an input resistance of 1.25 MΩ, and a bandwidth of 300 kHz. It functions within an extended industrial temperature range from –40°C to +125°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure the procurement channel sources production data directly from Texas Instruments or authorized distributors to guarantee component authenticity and traceability. Confirm that the delivered units match the exact part number designation without unauthorized modifications.

Selection Notes

Select this component when precise AC or DC voltage sensing requires reinforced isolation between high-voltage and low-voltage domains. The fixed 0.4 V/V gain and ±5 V input range suit applications interfacing with high-impedance signal sources. Consider the 8-pin SOIC package constraints and thermal dissipation requirements relative to the ambient operating environment.

Part Context

This device belongs to the AMC1350 family of precision isolated amplifiers manufactured by Texas Instruments. It utilizes delta-sigma modulation technology to achieve high accuracy and low drift across the specified temperature range. The DWVR suffix indicates the SOIC-8 surface-mount package configuration with tape-and-reel packaging.

Replacement Considerations

Consult the official datasheet for qualified alternative part numbers within the same product family. Verify pin compatibility and insulation ratings before substitution.
