AMC1106M05DWVR

ADCs/DACs - Special Purpose Overview

The AMC1106M05DWVR is a single-channel isolated delta-sigma modulator manufactured by Texas Instruments. It features a 16-bit resolution and operates with a sampling rate of 21 MS/s. The device supports analog and digital supply voltages ranging from 2.7V to 5.5V. Key electrical parameters include a signal-to-noise ratio (SNR) of 82.5 dB, a differential nonlinearity (DNL) of 0.99 LSB, an integral nonlinearity (INL) of 4 LSB, and a gain error of 0.005%. It consumes 45 mW of power and utilizes a serial data interface. The component is housed in an 8-SOIC package and functions within a temperature range of -40°C to 125°C.

ADCs/DACs - Special Purpose Feature Summary

• 16-bit resolution with 21 MS/s sampling rate
• Low DNL (0.99 LSB) and INL (4 LSB) for high precision
• Wide operating temperature range (-40°C to 125°C)
• Serial CMOS-compatible output interface

ADCs/DACs - Special Purpose Applications

• Precision current sensing in industrial automation
• Isolated data acquisition systems
• Motor control applications requiring high-speed modulation

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DWVR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the design accommodates the 2.7V to 5.5V supply voltage requirements for both analog and digital domains. Ensure compliance with RoHS3 standards if required by the target market regulations.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a high-speed, high-resolution isolated modulator is needed rather than a complete ADC. Compare against the AMC1106E05 variant if lower cost is prioritized over the 'M' grade performance specifications. Ensure the external sigma-delta ADC can handle the 21 MHz clock frequency generated by this modulator.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC1106 family of isolated delta-sigma modulators. It is distinct from the AMC1100 series, which are isolation amplifiers with lower bandwidth. The 'M05' designation indicates the specific gain and offset characteristics defined in the datasheet. It serves as the front-end stage for isolated measurement systems.

ADCs/DACs - Special Purpose Replacement Considerations

The AMC1106E05DWVR is a functional alternative within the same package, though it may have different performance grades. Verify pin compatibility and electrical parameter differences before substitution.
