AMC1304M05DW

ADCs/DACs - Special Purpose Overview

The AMC1304M05DW is a precision isolated sigma-delta modulator manufactured by Texas Instruments. It features a single channel with 16-bit resolution and supports a maximum clock frequency of 20.1 MHz. The device operates on dual power supplies ranging from 3 V to 5.5 V for both analog and digital sections. It provides galvanic isolation between the input and output sides, suitable for high-precision current sensing applications requiring ±50-mV input ranges.

ADCs/DACs - Special Purpose Feature Summary

• Isolated Sigma-Delta Modulator with 16-bit resolution
• Single-channel architecture supporting up to 20.1 MHz clock frequency
• Dual supply operation (3 V to 5.5 V) for analog and digital domains
• Designed for ±50-mV input precision current sensing

ADCs/DACs - Special Purpose Applications

• Precision current sensing in industrial automation
• Motor control systems requiring isolated feedback
• Power supply monitoring with high common-mode rejection

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type upon ordering, as the suffix 'DW' indicates a SOIC-16 tube packaging. Confirm moisture sensitivity level requirements for surface-mount assembly processes. Ensure the specific variant matches the required isolation voltage rating for the target application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single-channel isolated modulator with 16-bit resolution is required. Compare against the AMC1305 series if automotive qualification (AEC-Q100) or different input voltage ranges are needed. Verify that the external delta-sigma filter design aligns with the 20.1 MHz maximum clock frequency specification.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC1304 family of isolated modulators. It shares architectural similarities with the AMC1305 and AMC1306 series but differs in specific input voltage ranges and feature sets. The 'M05' designation typically refers to the gain and input range configuration within the product line.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes include other parts within the AMC130x family such as the AMC1304M05DWG4 or AMC1305M05DW variants, depending on whether automotive qualification or slight parameter adjustments are acceptable. Always verify pinout compatibility and isolation ratings before substitution.
