MAX5290BEUD+T

Digital To Analog Converters Overview

The MAX5290BEUD+T is a dual, 12-bit voltage-output digital-to-analog converter (DAC) from the Maxim Integrated MAX5290–MAX5295 family. It features buffered outputs with a maximum settling time of 3µs at the 12-bit level. The device operates from a 2.7V to 5.25V analog supply and a separate 1.8V to 3.6V digital supply. It utilizes a 20MHz 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols. The part includes two user-programmable digital I/O ports and software-selectable FAST and SLOW settling modes. It is specified over an extended temperature range of -40°C to +85°C and is housed in a 14-pin TSSOP package.

Digital To Analog Converters Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging when sourcing components. Confirm the 'B' grade designation corresponds to the specific integral nonlinearity and offset error specifications required for the application. Ensure the 14-pin TSSOP package matches the PCB footprint design. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Digital To Analog Converters Selection Notes

Select this component for applications requiring dual-channel precision voltage output with fast settling times. The B-grade specification offers ±2 LSB INL typical accuracy, suitable for general-purpose control loops. Consider the separate digital supply requirement if low-noise analog performance is critical. Evaluate the 14-pin TSSOP package constraints against available board space compared to the 16-pin Thin QFN alternative.

Digital To Analog Converters Part Context

This component belongs to the MAX5290–MAX5295 series of buffered, fast-settling, dual DACs. The MAX5290 variant specifically provides 12-bit resolution with unity-gain-configured output buffers. It shares the same serial interface architecture and pinout compatibility as the 10-bit and 8-bit variants within the family, facilitating design scalability across different resolution requirements.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same package include the MAX5290AEUD+T, which offers A-grade accuracy specifications. Other family members like the MAX5292EUD+T provide 10-bit resolution but maintain pin compatibility. Verify that any replacement maintains the required settling time and linearity specifications for the specific application context.
