MX7847KR+

Digital To Analog Converters Overview

The MX7847KR+ is a dual, 12-bit multiplying digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It features two independent channels with integrated output amplifiers and feedback resistors, delivering buffered voltage outputs capable of ±10V across a 2kΩ load. The device utilizes a 12-bit parallel interface with active-low chip select inputs for each channel and a common write input. Electrical specifications include a settling time of 4µs to within ±1/2 LSB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±1/2 LSB. It operates on positive and negative supply voltages ranging from 11.4V to 16.5V. The component is housed in a 24-pin Wide SOIC package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated output amplifiers and internal feedback resistors
• 12-bit parallel data interface with individual chip select inputs for independent or simultaneous operation
• Multiplying capability supporting unipolar and bipolar reference signal applications
• TTL and CMOS compatible logic levels without requiring external trimming

Digital To Analog Converters Applications

• Industrial process control systems
• Automatic test equipment
• Function generators and waveform reconstruction
• Digital offset and gain adjustments
• Machine and motion control systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix KR+ corresponds to the 24-pin Wide SOIC package and commercial temperature range when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain partners provide valid traceability records for this discontinued or limited-stock component family.

Digital To Analog Converters Selection Notes

Select the MX7847KR+ over the MX7837 variant when a native 12-bit parallel interface is required rather than an 8-bit bus structure. Verify that the system power supplies fall within the specified 11.4V to 16.5V range to maintain accuracy. Ensure the PCB layout accommodates the 24-pin Wide SOIC footprint and provides adequate thermal dissipation for the specified power ratings.

Digital To Analog Converters Part Context

This component belongs to the MX7837/MX7847 family of complete dual 12-bit multiplying DACs. It shares architectural similarities with other Maxim data converters but is distinct in its R-2R ladder structure and integrated amplifier design. The KR+ designation specifically identifies the surface-mount plastic small-outline package variant within the broader product line.
