MAX5291BEUE+

Digital To Analog Converters Overview

The MAX5291BEUE+T is a dual, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It features force-sense-configured output buffers and operates on a 2.7V to 5.25V analog supply with a separate 1.8V to AVDD digital supply. The device utilizes a 20MHz 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols. Key electrical specifications include a maximum settling time of 3µs at the 12-bit level, integral nonlinearity (INL) of ±2 LSB (max), differential nonlinearity (DNL) guaranteed monotonic at ±1 LSB (max), and an offset error of ±25mV (max). It includes two user-programmable digital I/O ports and supports software-selectable FAST and SLOW settling modes.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with force-sense-configured buffered outputs for enhanced drive capability.
• Software-selectable FAST and SLOW settling modes to optimize between speed and power consumption.
• Externally selectable power-up states allowing DAC outputs to initialize at zero scale, midscale, or full scale.
• Integrated user-programmable digital I/O ports accessible via the serial interface.

Digital To Analog Converters Applications

• Portable instrumentation
• Automatic test equipment (ATE)
• Digital offset and gain adjustment
• Programmable voltage and current sources

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with the required serial protocol configuration before procurement. Cross-reference the component marking code with the datasheet pinout to validate authenticity upon receipt.

Digital To Analog Converters Selection Notes

Select the MAX5291 variant specifically when force-sense output buffering is required rather than unity-gain configuration. Evaluate the need for the B-grade linearity specifications against application tolerance requirements. Confirm that the available 16-pin TSSOP package dimensions fit the target PCB layout constraints.

Digital To Analog Converters Part Context

This component belongs to the MAX5290–MAX5295 family of buffered, fast-settling, dual DACs. The MAX5291 specifically denotes the 12-bit resolution variant equipped with force-sense output buffers. It shares the same serial interface and control logic as the unity-gain MAX5290 and lower-resolution variants within the series.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same family include the MAX5290BEUE+ for unity-gain applications. Verify pin compatibility and buffer configuration differences when substituting with other members of the MAX529x series.
