MAX5351BEUA+T

Digital To Analog Converters Overview

The MAX5351BEUA+T is a low-power, 13-bit voltage-output digital-to-analog converter (DAC) with a precision output amplifier in an 8-pin µMAX package. It operates from a single +3.3V supply and draws only 280µA of supply current. The device features a double-buffered input register and DAC register, allowing independent or simultaneous updates. It supports SPI/QSPI and Microwire serial interfaces with Schmitt-trigger inputs for direct optocoupler interfacing. Key electrical parameters include a typical settling time of 16µs to ±1/2LSB, INL/DNL of ±1 LSB, and a reference bandwidth of 650kHz.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the '+T' designation aligns with RoHS compliance requirements for your assembly process. Check manufacturer documentation for availability status as this component may be subject to limited supply conditions. Ensure the ordering code matches the required temperature range and accuracy grade.

Digital To Analog Converters Selection Notes

Select the MAX5351 variant specifically for +3.3V single-supply applications, as the MAX535 requires +5V. Consider the ±1 LSB integral nonlinearity specification for precision requirements. Evaluate the need for the configurable output amplifier if signal conditioning or gain adjustment is necessary within the design. Verify that the serial interface timing meets the microcontroller's clock speed capabilities.

Digital To Analog Converters Part Context

This component belongs to the MAX535/MAX5351 family of low-power, 13-bit voltage-output DACs. The MAX5351 variant is distinguished by its +3.3V operating voltage, whereas the MAX535 operates at +5V. Both share identical pinouts, serial interface protocols, and architectural features, differing primarily in supply voltage specifications and reference input ranges.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the MAX5351AEUA+T for higher accuracy grades. Cross-family replacements require matching 13-bit resolution, serial interface compatibility, and supply voltage constraints. Verify pinout compatibility and thermal performance before substituting.
