MX7528JCWP

Digital To Analog Converters Overview

The MX7528JCWP+ is a dual-channel, 8-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes an R-2R resistor ladder architecture to provide two independent current outputs. The device features a parallel data interface and requires an external reference voltage for operation. Designed for surface-mount applications, it is housed in a 20-SOIC package with a width of 0.295 inches. The component operates on analog and digital supply voltages ranging from 5V to 15V. Key performance specifications include a settling time of 400ns, maximum integral nonlinearity (INL) of ±1 LSB, and maximum differential nonlinearity (DNL) of ±1 LSB. The industrial temperature range extends from 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 8-bit multiplying DACs within a single package.
• Multiplying capability allows the use of positive or negative reference voltages, including AC signals, to scale the output current.
• CMOS construction ensures low power consumption while maintaining high-speed parallel data transfer capabilities.
• Unbuffered current outputs facilitate flexible interfacing with external operational amplifiers for voltage conversion.

Digital To Analog Converters Applications

• Programmable gain amplifier circuits requiring precise attenuation or amplification control.
• Waveform generation systems where variable amplitude scaling is necessary.
• Digital potentiometer replacement applications needing higher resolution and linearity.
• Calibration equipment utilizing external reference sources for accurate signal adjustment.

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation when sourcing, as the JCWP variant denotes a commercial temperature range and SOIC package. Confirm RoHS compliance status through official manufacturer documentation, as legacy Maxim parts may have varying environmental certifications depending on production batch. Ensure that the parallel interface requirements match the host system's logic levels and timing constraints before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required for cost-sensitive designs needing 8-bit resolution. The parallel interface necessitates multiple GPIO pins; ensure sufficient microcontroller resources are available. For applications requiring lower pin counts, consider serial alternatives like the AD7528. Verify that the external reference voltage source can drive the input impedance without significant error, as the accuracy depends heavily on the reference stability.

Digital To Analog Converters Part Context

The MX7528 belongs to the broader MX7528/MX7628 family of multiplying DACs. While the MX7628 offers 12-bit resolution, the MX7528 provides 8-bit precision with faster settling times suitable for general-purpose analog control. This series represents a transition period in Maxim's portfolio, now managed by Analog Devices following the acquisition. The JCWP suffix specifically identifies the commercial grade version in the 20-pin small outline package.
