MAX11143ATI+T

Analog To Digital Converters (ADC) Overview

The MAX11143ATI+T is a high-speed, low-power serial successive-approximation register (SAR) analog-to-digital converter featuring 8-bit resolution and 16 input channels. It operates at a sampling rate of 500ksps with a full linear bandwidth of 1.5MHz. The device supports an external differential reference voltage ranging from 1V to VDD and functions on a single supply voltage between 2.35V and 3.6V, consuming 4.2mW at maximum speed. It includes a 16-entry FIFO, internal averaging for improved SNR, and SampleSet technology for programmable channel sequencing. The component utilizes an 8MHz 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ATI+T against official manufacturer documentation to confirm temperature range, tape-and-reel packaging, and lead-free status. Ensure compatibility with system requirements regarding the exposed pad thermal connection and digital I/O voltage levels before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 16-channel multiplexing is required alongside 8-bit resolution and 500ksps throughput. Consider the 1.5MHz full linear bandwidth for applications involving undersampling or high-frequency transient capture. Verify that the external reference requirement aligns with available system voltage rails.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11135–MAX11143 family of high-speed SAR ADCs manufactured by Analog Devices Inc./Maxim Integrated. The series differentiates primarily by resolution (12-, 10-, or 8-bit) and channel count (4, 8, or 16). The MAX11143 specifically addresses the need for high channel density with moderate resolution in space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include MAX11137 (12-bit, 16-channel) and MAX11140 (10-bit, 16-channel), provided higher resolution is acceptable. Cross-family replacements require verification of pinout compatibility and interface timing specifications.
