MX7542SQ/883B

Digital To Analog Converters Overview

The MX7542SQ/883B is a high-precision, monolithic 12-bit digital-to-analog converter manufactured by Analog Devices under the Maxim Integrated brand. It utilizes an R-2R resistor ladder architecture to convert parallel binary or offset binary digital inputs into analog current outputs. The device operates on a single 5V supply and features a CDIP-16 ceramic package suitable for through-hole mounting. Designed for military and aerospace environments, it supports a wide operating temperature range from -55°C to +125°C. Key electrical specifications include a settling time of 2 microseconds, a maximum slew rate of 2.5 mA, and linearity errors within 0.024%.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to restricted availability. Confirm that the specific suffix indicates compliance with MIL-STD-38535 quality standards. Check for lot traceability documentation required for aerospace procurement. Ensure storage conditions meet humidity sensitivity requirements for ceramic packages. Validate pin compatibility with existing PCB footprints before integration.

Digital To Analog Converters Selection Notes

Select this component when 12-bit resolution and wide industrial temperature ranges are mandatory. Compare against standard commercial variants if cost reduction is prioritized over radiation hardness. Consider the CDIP-16 package constraints during mechanical design. Evaluate power dissipation limits relative to system thermal management capabilities. Verify interface voltage levels match the host controller logic family.

Digital To Analog Converters Part Context

This part belongs to the MX7542 series of 12-bit DACs, representing a bridge between commercial precision and military durability. The SQ/883B designation specifically denotes screening according to MIL-STD-38535 Class K or H standards. It serves as a robust alternative to lower-grade commercial parts in critical infrastructure applications where failure is not an option.

Digital To Analog Converters Replacement Considerations

Direct replacements include AD7542GBQ for commercial equivalents or MX7542JCWE+ for surface-mount options. Verify pinout compatibility and electrical parameter overlaps before substitution. Note that package changes may require PCB redesign.
