MAX11205AEUB+T

Analog To Digital Converters (ADC) Overview

The MAX11205AEUB+T is a 16-bit, single-channel, ultra-low-power delta-sigma analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates on a 2.7V to 3.6V analog supply and a 1.7V to 3.6V digital supply, consuming less than 300µA in active mode and under 0.1µA in sleep mode. The device features fully differential signal inputs, an internal system clock of 2.4576MHz, and a 2-wire serial interface using SCLK and RDY/DOUT pins. Key electrical characteristics include a noise-free resolution of 16 bits, integral nonlinearity of ±20ppmFSR, and a data output rate of 120sps. It supports on-demand offset and gain self-calibration and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'AEUB+T' against the manufacturer's official documentation to confirm the internal oscillator frequency variant (2.4576MHz for 'A') and package type (10-pin µMAX). Ensure that the '+T' designation aligns with the intended reel packaging configuration as specified in the ordering information section of the datasheet. Cross-reference the RoHS compliance status indicated by the '+' symbol with current regulatory requirements for your region.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX11205AEUB+T when a 120sps output data rate is required, distinguishing it from the MAX11205BEUB+T which offers 13.75sps. This part is suitable for applications demanding high dynamic range with minimal power draw, such as sensors on 4mA to 20mA industrial control loops. Consider the fully differential input structure if common-mode noise rejection is critical for the signal source.

Analog To Digital Converters (ADC) Part Context

The MAX11205 series comprises 16-bit, single-channel, ultra-low-power delta-sigma ADCs designed for high-resolution, low-speed applications.
