MX7545AKN+

Digital To Analog Converters Overview

The MX7545AKN+ is a CMOS 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an R-2R resistor ladder architecture to provide high-resolution analog output from digital inputs. The device features a parallel data interface and delivers unbuffered current outputs, requiring external amplification for voltage applications. It operates with dual power supplies ranging from 5V to 15V for both analog and digital sections. Key performance metrics include a settling time of 1 microsecond, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) of ±1 LSB. It is housed in a 20-pin DIP package and supports an operating temperature range of 0°C to 70°C.

Digital To Analog Converters Feature Summary

• CMOS technology ensures low power consumption and compatibility with standard logic families.
• Multiplying capability allows the DAC output to vary proportionally with the reference voltage input.
• High precision R-2R ladder structure provides accurate linear conversion with minimal glitch energy.

Digital To Analog Converters Applications

• Precision instrumentation systems requiring stable analog signal generation.
• Industrial process control loops utilizing multiplying DAC functionality.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check for moisture sensitivity labeling if storage conditions exceed specified limits. Ensure packaging integrity matches the 20-PDIP specification to prevent pin damage during installation.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with multiplying reference capability is required. Consider the unbuffered current output nature; external operational amplifiers are necessary for voltage-mode applications. Verify that the parallel interface timing aligns with the host system's data bus constraints. Ensure supply voltages remain within the 5V to 15V range for optimal linearity performance.

Digital To Analog Converters Part Context

This part belongs to the MX7545 family of 12-bit multiplying DACs. It shares architectural similarities with other members like the MX7545JCWP+ but differs in package type and specific accuracy grades. The 'A' suffix typically denotes a specific binning or accuracy class within the product line, offering tighter INL/DNL specifications compared to standard variants.

Digital To Analog Converters Replacement Considerations

Direct replacements include LTC7545AKN#PBF, which offers identical electrical characteristics and pinout compatibility. Other MX7545 variants may serve as functional substitutes if package differences are accommodated. Verify that any substitute maintains the same R-2R architecture and multiplying reference requirements.
