MAX11633EEG+

Analog To Digital Converters (ADC) Overview

The MAX11633EEG+ is a serial 12-bit analog-to-digital converter (ADC) featuring an internal 2.5V reference and a 16-channel analog multiplexer with track-and-hold. It operates on a single supply voltage ranging from 2.7V to 3.6V and supports sampling rates up to 300ksps using an external clock. The device includes a 16-entry first-in/first-out (FIFO) buffer, scan mode, internal averaging, and AutoShutdown functionality. It utilizes a 10MHz SPI-/QSPI-/MICROWIRE-compatible interface and is housed in a 24-pin QSOP package, specified for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm lead-free status and RoHS compliance. Ensure the component matches the exact pinout and electrical specifications required for the target design. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with 16 single-ended channels is required within a low-voltage system. The internal 2.5V reference simplifies board layout by eliminating external reference components. Consider the 2.7V to 3.6V supply range and the 24-pin QSOP package dimensions during mechanical integration. Verify that the 300ksps maximum sampling rate meets the application's bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX11626–MAX11633 family of serial ADCs. It shares architectural similarities with the MAX11632 but differs in supply voltage and internal reference specifications. The family provides scalable channel counts and packaging options to accommodate various system monitoring and instrumentation needs.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11632 serves as a functional alternative within the same series, offering identical channel count and performance characteristics but operating at a higher supply voltage of 4.75V to 5.25V with a 4.096V internal reference.
