MAX5381NEUK

Digital To Analog Converters Overview

The MAX5381NEUK is an 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features a single voltage-buffered output and utilizes a current steering architecture. The device communicates via a 2-Wire serial interface compatible with I2C standards. It operates on analog and digital supply voltages ranging from 4.5 V to 5.5 V. Key performance metrics include a settling time of 20 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. The component is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates a voltage-buffered output stage for direct drive capability without external amplification.
• Supports standard 2-Wire serial communication protocols for simplified system interconnects.
• Utilizes current steering architecture to achieve specified linearity and speed within a compact footprint.

Digital To Analog Converters Applications

• Battery-powered instrumentation systems requiring low power consumption.
• Portable measurement devices utilizing single-supply operation.
• Industrial control loops needing precise analog signal generation.

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation when sourcing, as variations such as LEUK or NEUK may indicate different packaging or environmental compliance statuses. Confirm availability through authorized distributors, noting that some variants may be subject to discontinuation or limited stock. Ensure the selected part matches the required RoHS compliance and tape-and-reel specifications for automated assembly processes.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy requirements. The SOT-23-5 package is suitable for space-constrained designs. Consider the 4.5 V minimum supply voltage constraint; if lower voltage operation is needed, alternative parts from the family with wider input ranges should be evaluated. Verify that the 20 µs settling time meets the system's update rate requirements.

Digital To Analog Converters Part Context

The MAX5381 belongs to the Maxim Integrated low-cost, low-power DAC series designed for general-purpose applications. It shares architectural similarities with other members like the MAX5361 but offers higher 8-bit resolution compared to the 6-bit MAX5361. The NEUK suffix typically denotes a specific commercial grade variant in the SOT-23-5 package, distinguishing it from industrial or extended temperature options.

Digital To Analog Converters Replacement Considerations

The MAX5381LEUK+T is a verified equivalent part number offering identical electrical characteristics and pinout compatibility. Designers may also consider the MAX5361NEUK+T if reduced 6-bit resolution is acceptable for cost optimization. Always verify pin compatibility and software register mapping before substituting.
