MX7528CQ

Digital To Analog Converters Overview

The MX7528CQ is a dual-channel, 8-bit CMOS multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an R-2R resistor ladder architecture to provide two independent current outputs. The device features parallel data input and requires external reference voltage sources for operation. Designed for low power consumption, it operates on single or dual power supplies ranging from 5V to 15V. The component is housed in a 20-pin PLCC package with J-leads, suitable for surface-mount applications.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 8-bit DAC cores within a single package
• Multiplying capability allowing the use of positive, negative, or AC reference signals
• CMOS construction ensuring low power dissipation and compatibility with standard logic levels
• External reference design enabling flexible output scaling and signal conditioning

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring precise analog scaling
• Waveform generation circuits utilizing multiplying DAC functionality
• Digital potentiometer replacements in variable attenuation networks
• Battery-powered instrumentation systems benefiting from low power consumption

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CQ' against official Analog Devices documentation to confirm package type and temperature range, as suffixes often denote variations in housing or industrial ratings. Confirm RoHS compliance status through the manufacturer's latest certification documents. Ensure the source provides valid datasheets for the exact part number to avoid confusion with similar MX7528 variants that may have different pinouts or electrical characteristics.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required to save board space compared to using two single-channel DACs. Consider the R-2R architecture for its simplicity and cost-effectiveness in general-purpose applications. Verify that the parallel interface matches the host microcontroller's capabilities. Evaluate the need for external buffering if voltage output is required instead of the native current output.

Digital To Analog Converters Part Context

The MX7528 belongs to the Maxim Integrated family of high-performance CMOS DACs. This series is known for combining precision with low power consumption. The MX7528 specifically addresses applications needing two independent channels without the complexity of serial interfaces found in other models. It serves as a bridge between digital control systems and analog signal processing requirements.

Digital To Analog Converters Replacement Considerations

MX7528JN+ and MX7528JP+ are documented equivalents within the same product family. Verify pin compatibility and electrical specifications before substitution. Note that some variants may differ in package style or operating temperature range.
