ADS131M04IRUKT

Analog To Digital Converters (ADC) Overview

The ADS131M04IRUKT is a four-channel, simultaneously-sampling, 24-bit delta-sigma analog-to-digital converter manufactured by Texas Instruments. It operates with 2.7-V to 3.6-V analog and digital supplies and supports data rates up to 64 kSPS. The device features programmable gain from 1 to 128, achieving a dynamic range of 102 dB at gain 1 and 80 dB at gain 64. It includes an integrated low-drift 1.2-V reference, channel-to-channel phase calibration, and cyclic redundancy check (CRC) for communication integrity. The component is housed in a 20-pin WQFN package and functions within an operating temperature range of –40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the IRUKT suffix indicates the reel packaging variant of the WQFN package. Confirm the specific revision level matches system requirements, as datasheet updates may alter timing or register details. Ensure supply voltage sequencing adheres to the recommended operating conditions for both AVDD and DVDD domains.

Analog To Digital Converters (ADC) Selection Notes

Select this model when simultaneous multi-channel acquisition is required for energy metrology. The WQFN package offers a compact footprint suitable for space-constrained designs. Consider the internal reference and PGA integration to simplify the analog front-end circuitry compared to discrete solutions.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS131M series of high-precision ADCs designed for energy measurement applications. It shares architectural similarities with the ADS131M02 but provides four channels instead of two. The IRUKT designation specifies the tape-and-reel packaging format for automated assembly.
