MAX11040GUU+T

Analog To Digital Converters (ADC) Overview

The MAX11040GUU+T is a 24-bit, 4-channel, simultaneous-sampling sigma-delta analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features fully differential inputs with a ±2.2V full-scale range and overvoltage protection up to ±6V. The device operates from a single +3V supply and includes an internal crystal oscillator and reference. It supports cascading up to eight devices for 32-channel synchronization via SPI/QSPI/MICROWIRE interfaces. Key performance metrics include 117dB SNR at 1ksps and 106dB SNR at 16ksps.

Analog To Digital Converters (ADC) Feature Summary

• Four fully differential channels enable simultaneous sampling with programmable output data rates ranging from 0.25ksps to 64ksps.
• Built-in cascade logic allows daisy-chaining up to eight devices for synchronized multi-channel acquisition using a single serial interface command.
• Adjustable sampling phase provides internal compensation for phase shifts introduced by external dividers, transformers, or filters.

Analog To Digital Converters (ADC) Applications

• Power-protection relay equipment
• Multiphase power systems
• Industrial data-acquisition systems
• Medical instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GUU+T' against official documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the required operating temperature range of -40°C to +105°C. Confirm that the ordering information matches the exact revision level specified in the datasheet to avoid functional discrepancies.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-accuracy simultaneous sampling across multiple phases is required. The internal digital filter and programmable sampling delay simplify signal conditioning for power monitoring applications. Consider the cascading capability if system expansion beyond four channels is necessary without additional master controllers.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11040K/MAX11060 family of sigma-delta ADCs. The MAX11040K variant offers 24-bit resolution, while the MAX11060 provides 16-bit resolution. Both share identical pinouts and interface logic, differing primarily in resolution and dynamic performance specifications such as Signal-to-Noise Ratio.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11060GUU+ serves as a lower-resolution alternative within the same package and feature set. Verify that the reduced 16-bit resolution meets the system's accuracy requirements before substitution.
