MAX11201BEUB+

Analog To Digital Converters (ADC) Overview

The MAX11201BEUB+ is a 24-bit, single-channel, ultra-low-power delta-sigma analog-to-digital converter (ADC) manufactured by Maxim Integrated. It features a 2-wire serial interface with clock input and data output, housed in a 10-pin µMAX package. The device operates on an analog supply voltage of 2.7V to 3.6V and a digital supply voltage of 1.7V to 3.6V. It provides a maximum output data rate of 13.75 samples per second (sps). Key electrical characteristics include a noise-free resolution of 20.6 bits, integral nonlinearity of ±10 ppmFSR, and total operating current of 320µA maximum. It offers high common-mode rejection and power-supply rejection ratios.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm the specific suffix indicates lead-free and RoHS compliance as documented. Ensure the ordering part number matches the required output data rate variant. Check for any obsolescence notices from the manufacturer regarding this specific package type.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX11201BEUB+ when high DC accuracy and low power consumption are critical. This model provides a slower output rate compared to the A variant, suitable for static measurements. Ensure the external reference voltage falls within the specified differential range. Verify that the system can accommodate the 2-wire serial timing requirements for data retrieval.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1120x family of precision ADCs designed for high-resolution applications. It complements other models like the MAX11200 and MAX11202 which offer different channel counts or interface types. The BEUB+ designation specifically denotes the B grade performance level with a 10-pin µMAX package and compliant manufacturing status.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same series include the MAX11201AEUB+ for higher speed requirements. Other family members like the MAX11200 or MAX11202 may require schematic modifications due to differing pinouts or interface protocols.
