MX574ALCWI+

Analog To Digital Converters (ADC) Overview

The MX574ALCWI+ is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes Successive Approximation Register (SAR) architecture to achieve a sampling rate of 40 kSPS with a single-ended input configuration. The device operates on dual power supplies, requiring an analog supply range of ±11.4V to 16.5V and a digital supply of 5V. It features a parallel data interface and is housed in a 28-lead LC package (also referred to as 28-SOIC). The component supports external or internal reference types and includes an integrated sample-and-hold circuit with a 1:1 ratio relative to the ADC core.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed SAR ADC core with a dedicated sample-and-hold stage for accurate signal capture.
• Supports flexible voltage operation with wide-range analog supply inputs and standard 5V digital logic compatibility.
• Provides parallel data output for direct interfacing with microprocessors and DSPs without serial protocol overhead.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise analog signal digitization.
• Data acquisition modules for scientific instrumentation.
• Test and measurement equipment utilizing high-resolution analog front ends.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'LCWI+' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure that the design accommodates the required ±11.4V to 16.5V analog supply rails and 5V digital logic levels. Confirm RoHS3 compliance status for environmental regulations before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 40 kSPS throughput are sufficient for the application. Consider the parallel interface requirements and the need for dual power supplies. Compare against other SAR ADCs if lower power consumption or serial interfaces like SPI are preferred over raw speed and parallel simplicity.
