MX7228KP+

Digital To Analog Converters Overview

The MX7228KP+ is an 8-bit, 8-channel digital-to-analog converter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes an R-2R resistor ladder architecture to provide buffered voltage outputs. The device operates with a single +15V analog supply and a +5V digital supply, consuming 450 mW of power. It features parallel data interfaces and external reference capabilities. Designed for surface-mount applications, it is housed in a 28-pin PLCC package. The component supports an operating temperature range from -40°C to +85°C, ensuring reliability in industrial environments.

Digital To Analog Converters Feature Summary

• Integrates eight independent 8-bit DAC channels within a single compact package.
• Provides buffered voltage outputs suitable for driving low-impedance loads directly.
• Employs an R-2R resistor ladder structure for stable conversion performance.
• Supports parallel digital input interfaces for straightforward system integration.

Digital To Analog Converters Applications

• Multi-channel signal generation systems
• Industrial process control instrumentation

• Waveform generation circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans to ensure long-term supply stability.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated 8-bit voltage outputs are required in a space-constrained design. Ensure the application can accommodate the +15V analog and +5V digital supply rails. Verify that the parallel interface timing meets the system clock requirements. Consider thermal dissipation limits given the 450 mW power rating in the PLCC package.

Digital To Analog Converters Part Context

This part belongs to the MX7228 family of high-speed, multi-channel DACs. It shares architectural similarities with other members like the MX7226 but offers higher channel density. The device represents a transition period between Maxim Integrated and Analog Devices product lines, retaining the original Maxim branding in its part number while being distributed by ADI.

Digital To Analog Converters Replacement Considerations

The AD7228KPZ is a verified equivalent part number offering identical functionality and pinout compatibility. Both devices share the same 8-bit resolution, 8-channel configuration, and R-2R architecture. Verify package dimensions and thermal characteristics match the existing PCB layout before substitution.
