MAX5713AUD+

Digital To Analog Converters Overview

The MAX5713AUD+ is a quad-channel, low-power, 8-bit buffered voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features an internal reference selectable to 2.048V, 2.500V, or 4.096V, and accepts a wide supply voltage range of 2.7V to 5.5V with extremely low power consumption of 3mW. The device includes a 50MHz 3-wire SPI/QSPI/MICROWIRE/DSP-compatible serial interface with an RDY output for daisy-chain applications. DAC outputs are buffered, providing rail-to-rail operation with external references and settling times of 2.2µs. On power-up, the DAC outputs reset to zero, ensuring safety for driving valves or transducers.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolete part status indicators. Ensure ordering suffixes match specific package requirements such as TSSOP-14. Request original datasheets and test reports to validate electrical characteristics against specifications.

Digital To Analog Converters Selection Notes

Select this component when four independent 8-bit DAC channels are required in a compact form factor. Consider the MAX5713AUD+ for low-voltage applications due to its 2.7V minimum supply capability. Evaluate the internal reference options if external reference components need to be minimized. Verify that the 50MHz serial interface speed meets system timing requirements.

Digital To Analog Converters Part Context

The MAX5713 belongs to the MAX5713-MAX5715 family of ultra-small, quad-channel DACs. While the MAX5713 offers 8-bit resolution, the MAX5714 provides 10-bit accuracy, and the MAX5715 delivers 12-bit precision. All variants share identical pinouts, interfaces, and packaging options, allowing for design flexibility across different resolution requirements within the same hardware platform.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the MAX5714AUD+ and MAX5715AUD+. These parts maintain identical pin configurations and software compatibility while offering higher resolution bits. Verify that the increased resolution aligns with system accuracy needs before substitution.

Digital To Analog Converters FAQ

How does the MAX5713 handle power-up states?

On power-up, the MAX5713 automatically resets all DAC outputs to zero scale. This feature provides additional safety for applications driving valves or other transducers that must remain off during initialization.

What is the maximum serial interface clock frequency?

The device supports a 50MHz 3-wire SPI/QSPI/MICROWIRE/DSP-compatible serial interface. This high-speed interface allows for rapid data updates and supports daisy-chain applications via the RDY output.

Can the internal reference be disabled?

Yes, the internal reference is initially powered down upon reset to allow the use of an external reference. Users can enable the internal reference via software commands if an external reference is not utilized.
