MAX11040GUU+

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 operates from a single +3V supply and features fully differential inputs with ±6V overvoltage protection. The device supports cascading up to eight units for 32-channel synchronization via SPI/QSPI/MICROWIRE interfaces. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 106dB at 16ksps and 117dB at 1ksps. It offers programmable output data rates from 0.25ksps to 64ksps, adjustable sampling phases, and an internal crystal oscillator requiring a 24.576MHz external resonator.

Analog To Digital Converters (ADC) Feature Summary

• Four fully differential channels enable simultaneous sampling across all inputs without interleaving errors.
• Built-in cascade logic allows daisy-chaining up to eight devices for synchronized multi-channel acquisition using a single serial interface.
• Programmable sampling phase provides internal compensation for phase shifts introduced by external input dividers or filters.
• Integrated overvoltage protection safeguards analog inputs against damage from signals exceeding the full-scale range.

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+' indicates the 38-pin TSSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering code matches the exact temperature range and pin configuration required for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-accuracy energy measurement applications requiring precise phase alignment between multiple voltage and current channels. Consider the MAX11060 if 16-bit resolution is sufficient, as it shares the same pinout and functionality but offers lower noise performance requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11040K/MAX11060 family of simultaneous-sampling ADCs. It is designed specifically for power management systems where tracking varying frequencies and maintaining channel-to-channel gain matching is critical for accurate RMS calculations and harmonic analysis.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11060GUU+ is a functional substitute within the same family offering 16-bit resolution. Verify that the reduced dynamic range meets application SNR requirements before swapping.
