MAX1136EUA+

Analog To Digital Converters (ADC) Overview

The MAX1136EUA+ is a low-power, 10-bit analog-to-digital converter (ADC) from the MAX1136–MAX1139 family. It features four analog input channels and operates from a single supply of 4.5V to 5.5V. The device integrates a track/hold circuit, an internal 4.096V voltage reference, and an internal clock. It communicates via an I2C-compatible 2-wire serial interface supporting up to 1.7MHz in high-speed mode. Supply current is 670µA at 94.4ksps and drops below 1µA in AutoShutdown™ power-down mode. It is housed in an 8-pin µMAX package and guaranteed over the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a fully differential analog-input multiplexer with software-configurable unipolar or bipolar operation for single-ended or differential inputs.
• Features an internal 4.096V voltage reference and supports external references ranging from 1V to VDD.
• Includes an AutoShutdown™ function that powers down the device between conversions to minimize supply current.
• Supports high-speed I2C-compatible communication with data rates up to 1.7MHz.

Analog To Digital Converters (ADC) Applications

• Hand-held portable instruments
• Medical instruments
• Battery-powered test equipment
• Solar-powered remote systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure the design accommodates the required supply voltage range of 4.5V to 5.5V. Confirm that the system's I2C bus timing meets the specifications for high-speed mode if maximum sampling rates are utilized.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution is sufficient for the application requirements. Choose this part over higher-resolution variants if lower power consumption and reduced cost are priorities. Verify that the 4-channel input count aligns with the system's sensor interface needs.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1136–MAX1139 series of low-power, multichannel ADCs. It shares architectural similarities with the MAX1236–MAX1239 (12-bit) and MAX1036–MAX1039 (8-bit) families, which offer pin-compatible alternatives with different resolutions.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements include the MAX1236EUA+ (12-bit) and MAX1036EUA+ (8-bit). These parts share the same package and interface but differ in resolution and internal reference voltage characteristics.

Analog To Digital Converters (ADC) FAQ

What is the slave address for the MAX1136EUA+?

The factory-programmed slave address for the MAX1136/MAX1137 is 0110100.
