MX7521JN

Digital To Analog Converters Overview

The MX7521JN is an 8-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes a CMOS R-2R resistor ladder architecture to provide high-speed conversion with a typical settling time of 400 ns. The device features a parallel interface for data input and offers unbuffered current outputs. It operates on dual power supplies ranging from 5 V to 15 V for both analog and digital domains. The component is housed in a standard 16-pin narrow DIP package, suitable for through-hole mounting in industrial applications.

Digital To Analog Converters Feature Summary

• Multiplying capability allows the DAC output to vary proportionally with an external reference voltage.
• CMOS R-2R architecture ensures low power consumption and fast settling times.
• Unbuffered current output design provides flexibility for interfacing with external operational amplifiers.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise signal generation
• Programmable gain amplifier circuits
• Waveform generation equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix JN confirms the 16-pin narrow DIP package and commercial temperature range. Confirm RoHS compliance status as indicated by the '+' designation if applicable. Check manufacturer lifecycle status as older Maxim parts may be discontinued or subject to limited availability constraints.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with multiplying functionality is required in a through-hole format. Ensure the application can accommodate unbuffered current outputs and requires a parallel interface. Compare against the MX7521KN+ variant if surface-mount packaging is preferred instead of the DIP form factor.

Digital To Analog Converters Part Context

This part belongs to the MX752x series of multiplying DACs, which are widely used in legacy industrial designs. The MX7521 variant specifically denotes the 8-bit resolution within this family, sharing architectural similarities with higher-resolution models like the MX7523 and MX7524 while maintaining a compact 16-pin footprint.

Digital To Analog Converters Replacement Considerations

The MX7521KN+ serves as a direct pin-compatible replacement offering the same electrical specifications in a surface-mount SOIC-16 package. Verify that the PCB layout supports the alternative package dimensions if transitioning from the through-hole JN version.
