MAX5712EUT+T

Digital To Analog Converters Overview

The MAX5712EUT+T is a single-channel, 12-bit digital-to-analog converter (DAC) housed in a 6-pin SOT-23 package. It operates from a single +2.7V to +5.5V supply and features a rail-to-rail buffered voltage output. The device utilizes a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock frequencies up to 20MHz. It draws 85μA at +3V and enters a power-down mode consuming 0.3μA. The EUT suffix indicates an extended temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'EUT' to confirm the commercial temperature range (-40°C to +85°C). Ensure the '+T' designation matches the required reel packaging format. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a low-power, single-channel DAC is required in a minimal footprint. The resistor-string architecture ensures monotonic performance. Consider the MAX5711 if 10-bit resolution suffices, or the MAX5722/MAX5742 for dual/quad channel configurations. Verify that the 20MHz serial interface speed meets system timing requirements.

Digital To Analog Converters Part Context

The MAX5712 belongs to Maxim Integrated's family of ultra-small, low-power DACs. It serves as the single-channel counterpart to the quad-channel MAX5742. The device is designed for portable applications where space and battery life are critical constraints, offering high precision within a standard surface-mount package.

Digital To Analog Converters Replacement Considerations

The MAX5711 offers identical functionality with 10-bit resolution. For multi-channel needs, consider the MAX5722 (dual) or MAX5742 (quad). Verify thermal resistance and package dimensions match the existing PCB layout when substituting.

Digital To Analog Converters FAQ

What is the settling time for a half-scale transition?

The output settles to 1/2LSB in less than 10µs for a 1/4FS to 3/4FS transition when loaded with 5kΩ in parallel with 200pF.

How does the Power-On Reset (POR) function?

The POR circuit ensures the DAC output begins in a zero-volt state upon power-up by terminating the output to GND via a 100kΩ resistor.

Can the digital inputs interface directly with optocouplers?

Yes, all logic inputs are buffered with Schmitt triggers, allowing direct interfacing to optocouplers without additional external logic.
