MAX11635EEE+T

Analog To Digital Converters (ADC) Overview

The MAX11635EEE+T is a 12-bit successive-approximation register (SAR) analog-to-digital converter featuring four single-ended or two differential input channels. It operates from a single +2.7V to +3.6V supply and supports sampling rates up to 300ksps using an external clock. The device integrates a true differential track/hold, a 16-entry FIFO buffer, internal averaging, and AutoShutdown functionality. It utilizes a 10MHz SPI/QSPI/MICROWIRE-compatible serial interface and includes an internal reference voltage of 2.5V. The component is housed in a 16-pin QSOP package and is specified for operation over the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-entry first-in/first-out (FIFO) buffer to manage data flow without bus contention.
• Features an analog multiplexer with true differential track/hold supporting unipolar or bipolar inputs.
• Includes scan mode, internal averaging, and internal clock capabilities for flexible system control.
• Provides ±1 LSB integral nonlinearity and differential nonlinearity accuracy without missing codes.

Analog To Digital Converters (ADC) Applications

• System Supervision
• Data-Acquisition Systems
• Industrial Control Systems
• Patient Monitoring
• Data Logging

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'EEE' corresponds to the 16-pin QSOP package and '+T' indicates tape-and-reel packaging. Confirm the specific voltage supply requirements align with the +2.7V to +3.6V specification for the MAX11635 variant. Ensure compatibility with the required serial interface protocol before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 300ksps sampling rate are required within a low-voltage 3.3V system environment. Consider the MAX11635EEE+T over other family members if four single-ended or two differential channels are sufficient. Evaluate the need for the integrated FIFO and internal averaging features against external buffering requirements.

Analog To Digital Converters (ADC) Part Context

The MAX11635EEE+T belongs to the MAX11634–MAX11637 series of 12-bit, 300ksps ADCs. This family shares common architectural features such as the SAR conversion technique, serial interface, and FIFO structure. The primary distinction lies in the number of input channels and the supported supply voltage ranges, with the MAX11635 specifically designed for lower voltage applications compared to the MAX11634.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11634EEE+T serves as a functional substitute but requires a +4.75V to +5.25V supply instead of the +2.7V to +3.6V range. Verify power supply compatibility and pinout alignment when considering cross-family replacements within the MAX1163x series.
