MAX11609EEE+

Analog To Digital Converters (ADC) Overview

The MAX11609EEE+ is a low-power, 10-bit analog-to-digital converter (ADC) featuring eight single-ended or four fully differential analog input channels. It operates from a single supply of 2.7V to 3.6V and integrates an internal track/hold circuit, voltage reference, and clock. The device utilizes an I2C-compatible 2-wire serial interface supporting data rates up to 1.7MHz. It achieves a maximum sampling rate of 94.4ksps with a typical supply current of 670µA. AutoShutdown technology reduces power consumption to less than 1µA at low throughput rates. The component is housed in a 16-pin QSOP package and is guaranteed to operate over the extended temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead-free status. Ensure the design accommodates the required supply voltage range of 2.7V to 3.6V. Confirm that the I2C bus timing meets the Fast Mode or High-Speed Mode requirements for the target application throughput. Check for any specific environmental compliance documentation if required by the end product regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight analog channels are required within a 10-bit resolution constraint. Choose the MAX11609EEE+ over pin-compatible variants like the MAX11608 or MAX11611 based on the specific channel count and internal reference voltage needs. Consider the 16-pin QSOP package dimensions for PCB layout constraints. Evaluate the power budget against the 670µA active current and sub-1µA shutdown current specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11606–MAX11611 family of low-power, multichannel ADCs. It shares architectural similarities with the MAX11608 and MAX11611, differing primarily in channel count and internal reference voltage. Pin-compatible alternatives include the 12-bit MAX11612–MAX11617 series and the 8-bit MAX11600–MAX11605 series for designs requiring different resolution or channel configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes include the MAX11608EEE+ and MAX11611EEE+. Verify functional equivalence regarding channel count and reference voltage before substitution.
