AMC1106M05DWV

ADCs/DACs - Special Purpose Overview

The AMC1106M05DWV is a single-channel isolated delta-sigma modulator manufactured by Texas Instruments. It features a ±50-mV input voltage range, making it suitable for direct connection to shunt resistors in precision current sensing applications. The device utilizes a capacitive isolation barrier with high electromagnetic interference immunity. It operates on dual power supplies: AVDD (3.3 V or 5 V) for the analog side and DVDD (3.0 V, 3.3 V, or 5 V) for the digital interface. Key electrical parameters include 16-bit resolution, a sampling rate of 21 MS/s, and a power consumption of 45 mW. The component is housed in an 8-SOIC package and supports serial CMOS output.

ADCs/DACs - Special Purpose Feature Summary

• Isolated Delta-Sigma Modulator with ±50-mV input range optimized for low-side and high-side current sensing
• High CMTI performance via robust capacitive isolation barrier
• Manchester-encoded CMOS digital interface for reliable data transmission
• System-level diagnostic capabilities integrated into the design

ADCs/DACs - Special Purpose Applications

• Multi-phase energy metering systems requiring AC/DC current measurement
• Precision current sensing in motor drives and inverters
• Industrial automation equipment utilizing shunt-based current detection

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DWV' corresponds to the tape-and-reel packaging format when ordering. Confirm that the required isolation voltage ratings meet the system's safety standards. Ensure the host microcontroller supports the Manchester encoding protocol required by the AMC1106M05DWV interface.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a small form factor is required for ±50-mV signal inputs. Compare against the AMC1106E05 variant if extended industrial temperature ranges are necessary beyond the standard specifications. Ensure the application can accommodate the 21 MS/s output bitstream for subsequent digital filtering.

ADCs/DACs - Special Purpose Part Context

The AMC1106M05DWV belongs to the AMC1106 family of basic isolated delta-sigma modulators. It shares architectural similarities with the AMC1306 but is specifically optimized for lower input voltage ranges. This part serves as a front-end converter for digital isolators or microcontrollers in high-noise environments.

ADCs/DACs - Special Purpose Replacement Considerations

The AMC1106E05DWVR is a related variant within the same family. Verify if the E05 suffix meets specific environmental or performance requirements different from the M05 version before substitution.
