MX7576AQ

Analog To Digital Converters (ADC) Overview

The MX7576AQ is an 8-bit successive-approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated. It features a conversion time of 10 microseconds and operates on a single +5V supply with a 1.23V external reference. The device accepts input voltages from 0V to 2VREF and offers a data-access time of 100ns. Total unadjusted error is limited to ±1LSB maximum, ensuring accurate digitization for microprocessor-compatible applications requiring low power dissipation.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-compatible 8-bit parallel interface
• Successive-approximation conversion technique
• Single +5V supply operation
• Low power consumption profile

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Digital signal processing units
• Telecommunications equipment
• Audio systems
• Low-power data loggers

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation matches Maxim Integrated or Analog Devices Inc. Confirm the package type is CDIP-18 and the temperature range covers -25°C to +85°C. Ensure the datasheet revision aligns with part number MX7576AQ to distinguish it from the MX7575 variant which includes an internal track/hold function. Check for authentic markings to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-microsecond conversion speed is sufficient for the application, distinguishing it from the faster MX7575. It is suitable for designs requiring a simple parallel interface without the need for an internal sample-and-hold amplifier. Consider the 1.23V external reference requirement and the 0V to 2VREF input range during circuit design.

Analog To Digital Converters (ADC) Part Context

The MX7576AQ belongs to the MX757x family of high-speed CMOS ADCs. It shares architectural similarities with the MX7575 but lacks the built-in track/hold function, resulting in a slower 10-microsecond conversion time compared to the MX7575's 5-microseconds. Both devices utilize successive-approximation logic and are designed for microprocessor integration.

Analog To Digital Converters (ADC) Replacement Considerations

MX7575 serves as a functional substitute if the application requires a faster 5-microsecond conversion time and benefits from the integrated track/hold capability. Other MX757x variants may offer different resolutions or speeds but require verification of pin compatibility and electrical specifications.
