MAX11137ATI+

Analog To Digital Converters (ADC) Overview

The MAX11137ATI+ is a 12-bit, 16-channel successive-approximation register (SAR) analog-to-digital converter (ADC). It operates at a sampling rate of 500ksps with a full linear bandwidth of 1.5MHz. The device supports single-ended, fully differential, and pseudo-differential input configurations. It features an integrated FIFO, internal averaging for improved SNR, and SampleSet technology for user-defined channel sequencing. Power consumption is 4.2mW at 500ksps with a 3V supply, dropping to 2µA in shutdown mode. It utilizes an 8MHz, 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'ATI+' against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure compatibility with system voltage requirements, specifically the 2.35V to 3.6V analog supply and 1.5V to 3.6V digital I/O supply ranges. Confirm RoHS compliance status if required by your manufacturing standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high channel count (16) and moderate resolution (12-bit) are required in a compact form factor. It is suitable for applications needing flexible input configurations and low power consumption. Consider the 28-pin TQFN package constraints and thermal dissipation requirements for your PCB layout. Verify that the 1.5MHz full linear bandwidth meets the signal frequency requirements of your application.

Analog To Digital Converters (ADC) Part Context

The MAX11137 is part of the MAX11135–MAX11143 family of high-speed, low-power ADCs from Analog Devices/Maxim Integrated. This family shares common architectural features such as the SAR architecture, serial interface, and power management options. Variations within the family primarily differ in resolution (12-bit, 10-bit, or 8-bit) and channel count (4, 8, or 16 channels).

Analog To Digital Converters (ADC) Replacement Considerations

Check the manufacturer's website for recommended products and related parts. Direct replacements may include other members of the MAX11135–MAX11143 series with different resolutions or channel counts, provided they fit the pinout and performance requirements.
