MAX11633EEG+T

Analog To Digital Converters (ADC) Overview

The MAX11633EEG+T is a serial 12-bit analog-to-digital converter (ADC) with an internal reference, packaged in a 24-pin QSOP. It features 16 single-ended analog input channels and supports sampling rates up to 300ksps using an external clock. The device operates from a single +2.7V to +3.6V supply and includes a 16-entry first-in/first-out (FIFO) buffer. It integrates scan mode, internal averaging, and AutoShutdown functionality. The ADC utilizes a 10MHz SPI-/QSPI-/MICROWIRE-compatible serial interface for data communication.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the MAX11633 family may be discontinued or subject to limited availability. Confirm RoHS compliance and lead-free packaging specifications against current manufacturer documentation. Ensure the ordering suffix matches the required package type and temperature range. Cross-reference the datasheet revision to validate electrical characteristics prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 16 single-ended inputs within a compact 24-pin QSOP footprint. Verify that the system power supply falls within the 2.7V to 3.6V operating range. Consider the internal 2.5V reference voltage when designing signal conditioning circuits. Evaluate the need for FIFO buffering if the host processor cannot keep pace with the maximum 300ksps sampling rate.

Analog To Digital Converters (ADC) Part Context

The MAX11633 belongs to the MAX11626–MAX11633 family of 12-bit serial ADCs. It shares architectural similarities with the MAX11632 but differs in supply voltage requirements and internal reference voltage. The family provides scalable channel counts ranging from 4 to 16 inputs across various packages, maintaining consistent serial interface protocols and accuracy specifications.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11632EEG+ serves as a functional substitute for systems operating at +5V supplies, utilizing a 4.096V internal reference instead of 2.5V. Verify pin compatibility and register configuration differences before substitution. Other family members like the MAX11628 offer fewer channels and different package options.
