MX7225KN+

Digital To Analog Converters Overview

The MX7225KN+ is a quad, 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features an R-2R resistor ladder architecture with integrated voltage-output amplifier latches for buffered analog signals. The device utilizes a parallel word input interface and operates on dual power supplies ranging from -5 V to +16.5 V for both analog and digital domains. Key performance metrics include a settling time of 4 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It is housed in a 24-pin SOIC package and supports an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 8-bit DAC channels with built-in output amplifiers
• Utilizes CMOS R-2R architecture for high-speed conversion
• Supports parallel data input formats for direct microprocessor interfacing
• Provides buffered voltage outputs with latch capability

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation with battery-powered operation constraints
• Data acquisition systems needing precise analog reference voltages
• Automotive electronic control units for sensor simulation

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or manufacturer-certified channels due to the presence of obsolete variants in the market. Confirm RoHS compliance status as legacy Maxim Integrated parts may have varying environmental certifications depending on the specific production batch. Ensure the ordering suffix matches the required package type and temperature grade to avoid functional mismatches during integration.

Digital To Analog Converters Selection Notes

Select this component when a compact solution for multiple low-resolution analog outputs is required without external buffering circuitry. Compare against the AD7225 series if wider industrial temperature ranges or through-hole packaging are necessary. Evaluate power supply requirements carefully, as the device mandates dual rails including a negative voltage rail for proper operation of the output stage.

Digital To Analog Converters Part Context

This part belongs to the MX7225 family of quad 8-bit DACs produced by Maxim Integrated, now part of Analog Devices. The family includes variations such as the MX7225KCWG+ and MX7225CQ, differing primarily in package style and temperature rating. These devices were designed to replace older bipolar DAC technologies with more power-efficient CMOS alternatives while maintaining comparable speed and accuracy specifications.

Digital To Analog Converters Replacement Considerations
