MX7845KR

Digital To Analog Converters Overview

The MX7845KR is a high-speed, 12-bit multiplying digital-to-analog converter (MDAC) manufactured by Analog Devices Inc. and Maxim Integrated. It features an R-2R resistor ladder architecture with a buffered voltage output stage. The device operates on a single +5V to +15V supply and accepts parallel digital inputs. Key electrical specifications include a settling time of 1 microsecond and integral nonlinearity (INL) of ±0.5 LSB. It is housed in a 20-pin SOIC package.

Digital To Analog Converters Feature Summary

• Multiplying capability allows the reference input to function as a signal input for variable gain applications.
• Integrated output buffer provides low impedance drive for subsequent stages without external components.
• High-speed performance enables rapid settling times suitable for dynamic signal processing.
• Single-supply operation simplifies power distribution in portable and industrial systems.

Digital To Analog Converters Applications

• Portable instrumentation requiring precise analog signal generation
• Industrial process control loops needing programmable gain amplifiers
• Battery-powered test equipment utilizing single-supply architectures

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature range. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements. Confirm RoHS compliance status through manufacturer documentation before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and 1-microsecond settling time are required within a single-supply environment. Compare against the MX7545AKEWP+T if lower INL or different packaging is needed. Evaluate power consumption constraints relative to the internal reference and buffer circuitry.

Digital To Analog Converters Part Context

This part belongs to the MX7845 family of multiplying DACs. It shares architectural similarities with the AD7845 series but differs in supply voltage ranges and specific performance metrics. The product line targets applications demanding moderate speed and precision in compact form factors.

Digital To Analog Converters Replacement Considerations

MX7845JR-T serves as a direct pin-compatible alternative with identical functionality. MX7545AKEWP+T offers similar specifications but may require verification of package dimensions and thermal characteristics for direct substitution.
