MAX11601EKA+T

Analog To Digital Converters (ADC) Overview

The MAX11601EKA+T is an 8-bit successive-approximation analog-to-digital converter (ADC) featuring four software-configurable analog input channels. It operates from a single supply voltage ranging from 2.7V to 3.6V and supports sampling rates up to 188ksps with a typical supply current of 350µA. The device integrates a 2.048V internal reference, track/hold circuitry, and an I²C-compatible 2-wire serial interface supporting data rates up to 1.7MHz. It utilizes AutoShutdown technology to reduce power consumption to less than 1µA during low-throughput operations. The component is housed in an 8-pin SOT-23 package and is guaranteed to operate within the extended industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 2-wire serial interface compatible with I²C protocols, supporting both Fast Mode and High-Speed Mode for efficient data transfer.
• Features AutoShutdown technology that powers down the device between conversions, significantly reducing supply current at lower throughput rates.
• Includes an internal 2.048V voltage reference and clock, eliminating the need for external components while allowing for external reference inputs.

Analog To Digital Converters (ADC) Applications

• Handheld portable applications
• Medical instruments
• Battery-powered test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct pinout and package configuration. Confirm RoHS compliance status and lead-free certification requirements prior to procurement. Ensure the selected variant matches the required supply voltage range and channel count for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a compact 8-bit ADC with multiple input channels is required for battery-operated systems. Verify that the 2.7V to 3.6V supply range aligns with the system power architecture. Consider the 188ksps maximum sampling rate and I²C interface speed to ensure compatibility with the host microcontroller's communication capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11600–MAX11605 family of low-power, multichannel ADCs. While sharing similar architectures, variants differ in channel count and internal reference voltage. The MAX11601 specifically provides four channels with a 2.048V internal reference, distinguishing it from the MAX11600 which offers the same channel count but with a 4.096V reference.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11600EKA+T serves as a direct functional substitute within the same package, differing primarily in its internal reference voltage specification.
