MAX534BEPE

Digital To Analog Converters Overview

The MAX534BEPE is a quad, 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +4.5V to +5.5V supply and features rail-to-rail buffered voltage outputs. The device utilizes a double-buffered serial interface compatible with SPI, QSPI, and Microwire protocols, supporting clock rates up to 10MHz. Key electrical specifications include an INL of ±2 LSB and DNL of ±1 LSB for the B-grade variant. Supply current is 0.8mA during operation and drops to 2.5µA in shutdown mode. The component is housed in a 16-pin Plastic DIP package and supports an industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Quad-channel architecture with independent software control for each DAC output
• Double-buffered registers enabling synchronous updating of all channels via a single command
• Rail-to-rail output buffer amplifiers capable of driving resistive and capacitive loads
• Integrated power-down mode significantly reduces supply current consumption

Digital To Analog Converters Applications

• Digital gain and offset adjustments in signal processing chains
• Programmable attenuators for RF and audio applications
• Portable instruments requiring low-power analog generation
• Programmable current sources for sensor biasing

Digital To Analog Converters Procurement Notes

Verify the specific suffix BEPE corresponds to the -40°C to +85°C temperature grade and 16-PDIP package when sourcing. Confirm RoHS compliance status as indicated on the manufacturer's official documentation. Ensure the supplier provides the original datasheet to validate the pinout and electrical characteristics against the official Maxim Integrated specification sheet.

Digital To Analog Converters Selection Notes

Select this component for designs requiring four independent 8-bit voltage outputs within a single IC footprint. The rail-to-rail output capability simplifies single-supply system design by eliminating the need for negative rails. Verify that the 10MHz serial interface speed meets the microprocessor's timing requirements. Consider the 0.8mA active current consumption if battery life is a critical constraint in portable applications.

Digital To Analog Converters Part Context

The MAX534 belongs to the Maxim Integrated family of low-power, +5V digital-to-analog converters. It is functionally similar to the MAX533 but optimized for standard +5V logic levels. The BEPE designation specifically identifies the commercial/industrial temperature version in a plastic dual in-line package, distinguishing it from the ceramic or surface-mount variants available in the broader product line.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MAX534 variants such as MAX534ACEE or MAX534BEEE, provided the package type and temperature range match the design requirements. Cross-referencing with the manufacturer's obsolescence notices is recommended to ensure long-term availability.
