MX7548KCWP+

Digital To Analog Converters Overview

The MX7548KCWP+ is a CMOS, 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features a single channel with an R-2R resistor ladder architecture and parallel data interface. The device provides unbuffered current output and operates on dual power supplies ranging from 4.75 V to 5.25 V or 11.4 V to 15.75 V. Key performance specifications include a settling time of 1 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. It functions within a commercial temperature range of 0°C to +70°C and is housed in a 20-pin SOIC package.

Digital To Analog Converters Feature Summary

• Multiplying capability allows the analog output to vary proportionally with the reference voltage input.
• CMOS construction ensures low power consumption while maintaining high-speed conversion characteristics.
• Integrated R-2R ladder network provides precise digital-to-analog signal translation without external components.

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring precise attenuation or amplification factors.
• Voltage-controlled filters where frequency or Q-factor adjustment is needed via digital codes.
• Digital potentiometer replacements for variable resistance applications in signal conditioning chains.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'KCWP+' against the official manufacturer datasheet to confirm pinout compatibility and RoHS status. Ensure that the selected package variant matches the intended PCB footprint. Confirm supply chain authenticity through authorized distributors to avoid counterfeit components. Check for any recent product change notifications regarding material composition or manufacturing site changes.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and multiplying functionality are required in a compact surface-mount package. Compare settling time and linearity specifications against system requirements to ensure adequate precision. Consider the parallel interface complexity versus serial alternatives if pin count is constrained. Verify that the available supply voltage ranges align with the system's power rails.

Digital To Analog Converters Part Context

This part belongs to the Maxim Integrated MX7548 series of high-performance DACs. The series typically includes variants with different resolutions, such as the 8-bit MX7528 and 14-bit MX7538. These devices share common architectural features like the R-2R ladder structure but differ in pin counts and performance metrics tailored for specific application needs.

Digital To Analog Converters Replacement Considerations

Direct substitutes may include other parts from the MX7548 family with compatible pinouts. Cross-reference with similar 12-bit multiplying DACs from other manufacturers if availability is limited. Ensure that replacement parts meet the same electrical specifications and package dimensions for drop-in compatibility.
