MAX11123ATI+T

Analog To Digital Converters (ADC) Overview

The MAX11123ATI+T is a 10-bit successive-approximation register (SAR) analog-to-digital converter (ADC) from the MAX11120–MAX11128 family. It features an 8-channel multiplexer with true differential track/hold and operates at a sampling rate of 1Msps. The device supports both internal clock mode, which includes a 16-entry FIFO and internal averaging for improved SNR, and external clock mode utilizing SampleSet technology for user-defined channel sequencing. It requires an external differential reference and operates on a single 2.35V to 3.6V supply, consuming 5.4mW at 1Msps.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current part numbering system to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component matches the required thermal and electrical specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 10-bit accuracy and 1Msps throughput with low power consumption. Choose the internal clock mode if FIFO buffering and internal averaging are needed to improve SNR. Use the external clock mode with SampleSet technology to reduce microcontroller overhead in multichannel scanning applications. Ensure the analog input range matches the bipolar or unipolar configuration settings.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11120–MAX11128 series of high-speed, low-power serial ADCs. The '11123' designation specifically indicates a 10-bit resolution variant within the family, which also includes 12-bit (MAX11120/23/26) and 8-bit (MAX11121/24/27) options. All variants share the same pinout and core architecture but differ in resolution and dynamic performance metrics.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include MAX11120 (12-bit) and MAX11121 (8-bit), provided the resolution difference is acceptable. Cross-family replacements require matching SAR architecture, 1Msps speed, and TQFN-28 packaging.
