MX7541KCWN+

Digital To Analog Converters Overview

The MX7541KCWN+ is a 12-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 high-resolution analog output from parallel digital inputs. The device features a unbuffered current output and supports external reference configurations. It operates on dual power supplies ranging from 5 V to 16 V for both analog and digital domains. The component is housed in an 18-pin narrow DIP package designed for through-hole mounting. Key performance metrics include a settling time of 1 µs, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±0.5 LSB. The operational temperature range extends from 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Multiplying capability allows the analog output to vary proportionally with the external reference voltage.
• CMOS technology ensures low power consumption while maintaining fast settling times.
• Parallel interface enables direct connection to standard microprocessors and logic systems.

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring precise attenuation or amplification factors.
• Waveform generation circuits where signal amplitude must be digitally controlled.
• Digital potentiometer replacements in applications demanding higher linearity and lower noise.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'KCWN+' against official Analog Devices documentation to confirm pinout compatibility and RoHS status. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity, as obsolete series may have limited availability. Confirm that the narrow DIP package aligns with existing PCB footprints before procurement.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with multiplying functionality is required in a through-hole design. Ensure the application can accommodate the unbuffered current output, potentially requiring an external operational amplifier for voltage conversion. Verify that the system's digital logic levels are compatible with the specified supply voltage range of 5 V to 16 V.

Digital To Analog Converters Part Context

This device belongs to the MX7541A family of CMOS multiplying DACs. It serves as a successor to earlier bipolar versions like the AD7541, offering improved power efficiency and integration. The part is widely recognized in industrial control and instrumentation for its balance of precision and ease of use in legacy through-hole designs.

Digital To Analog Converters Replacement Considerations

The LTC7541AKN#PBF is a verified functional replacement within the Analog Devices portfolio, offering similar specifications in a PDIP-18 package. Other variants such as the MX7541AJCWN+ provide equivalent electrical performance but utilize surface-mount packaging, requiring PCB redesign if used as a drop-in substitute.
