MAX11124ATI+

Analog To Digital Converters (ADC) Overview

The MAX11124ATI+T is a 10-bit, 8-channel successive-approximation register (SAR) analog-to-digital converter (ADC). It operates from a 2.35V to 3.6V supply and achieves a conversion rate of 1Msps with no pipeline delay. The device features a 1.5MHz full linear bandwidth and consumes 5.4mW at 1Msps with 3V supplies. It includes an integrated FIFO, internal averaging for SNR improvement, and SampleSet technology for user-defined channel sequencing. The component utilizes a 16MHz, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ATI+' against the manufacturer's current product status documentation. Confirm RoHS compliance and lead finish specifications directly from the official datasheet or authorized distributor listings prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight single-ended or differential input channels are required. Ensure the application supports the 2.35V to 3.6V analog supply range and 1.5V to 3.6V digital I/O supply. Verify that the 10-bit resolution meets system accuracy requirements alongside the specified ±1 LSB linearity errors.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11120–MAX11128 family of high-speed, low-power SAR ADCs. The MAX11124 variant specifically provides 10-bit resolution and eight analog input channels within the standard 28-pin TQFN package form factor shared across the series.

Analog To Digital Converters (ADC) Replacement Considerations

Other members of the MAX1112x family offer different resolutions (8-bit or 12-bit) or channel counts (4 or 16). Verify pin compatibility and electrical parameter alignment before substituting with variants such as the MAX1120 or MAX1128.
