AMC1350DWV

Overview

The AMC1350DWV is a precision reinforced isolated amplifier manufactured by Texas Instruments, designed for high-accuracy signal transmission across isolation barriers. It features a linear input voltage range of ±5V and a fixed gain of 0.4V/V. Key electrical specifications include a maximum offset voltage error of ±1.5mV, a maximum gain error of ±0.2%, and a minimum common-mode transient immunity (CMTI) of 100kV/µs. The device operates on dual supplies of 3.3V or 5V and supports an industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides enhanced electrical isolation certified up to 5kVRMS, protecting low-voltage circuitry from harmful voltage transients.
• Features high input impedance optimized for connection with high-impedance resistive dividers or voltage sources with high output resistance.
• Delivers excellent DC accuracy with low drift characteristics, supporting precise measurements in demanding industrial environments.

Applications

• Isolated AC voltage detection in motor drive systems
• Voltage sensing in variable frequency drives
• Protection relay applications requiring galvanic isolation

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm package type and tape/reel configuration. Ensure the selected variant meets the required safety certification standards for your application. Cross-reference the ordering part number with the latest datasheet revision to avoid discrepancies in pinout or electrical ratings.

Selection Notes

Select this component when high-precision voltage measurement is required across a robust isolation barrier. The ±5V input range suits direct sensing applications without extensive scaling. Consider the fixed 0.4V/V gain for system-level signal conditioning needs. Evaluate the CMTI rating against the noise environment of the switching power stage.

Part Context

This device belongs to the AMC1350 family of precision isolated amplifiers from Texas Instruments. It utilizes optical isolation technology to achieve high CMTI performance compared to capacitive alternatives. The DWV designation indicates an 8-pin SOIC package variant within the broader product line.

Replacement Considerations

Consult the official TI selection guide for compatible alternatives within the AMC series. Verify that any substitute maintains the same isolation voltage rating and input range requirements.
