MAX534BEEE

Digital To Analog Converters Overview

The MAX534BEEE is a quad, 8-bit digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates on a single +4.5V to +5.5V supply and features rail-to-rail buffered voltage outputs. The device utilizes a double-buffered serial interface compatible with SPI, QSPI, and Microwire protocols. Key electrical specifications include an INL of ±2 LSB and DNL of ±1 LSB. Operating current is 0.8mA, reducing to 2.5µA in shutdown mode. The component is housed in a 16-pin QSOP package and supports an industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Quad-channel architecture with independent software control for each DAC output
• Double-buffered registers enabling synchronous updating of all channels
• Rail-to-rail output buffers capable of driving resistive or capacitive loads
• Serial data output pin facilitates daisy-chaining multiple devices

Digital To Analog Converters Applications

• Digital gain and offset adjustments
• Programmable attenuators
• Portable instruments

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EEE' confirms the 16-pin QSOP package and -40°C to +85°C temperature rating. Confirm RoHS compliance status as indicated by the '+' designation in the part number. Ensure the source document matches the official Maxim Integrated datasheet for accurate pinout and timing parameters.

Digital To Analog Converters Selection Notes

Select this component when four independent 8-bit voltage outputs are required within a low-power system. The MAX534BEEE is suitable for applications needing rail-to-rail swing without negative supplies. Verify that the host microcontroller supports the required SPI, QSPI, or Microwire interface modes.

Digital To Analog Converters Part Context

The MAX534 series includes variants such as the MAX534ACPE and MAX534BEPE, which differ primarily in temperature range and package type. The MAX534BEEE specifically denotes the commercial grade extended temperature version in the small outline package. This model belongs to the broader family of low-power, single-supply DACs designed for portable electronics.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MAX534 variants like the MAX534BCEE for different packaging needs. Cross-referencing with the MAX533 is recommended if operation down to 2.7V is required instead of the standard 4.5V minimum.

Digital To Analog Converters FAQ

How does the MAX534 handle simultaneous updates of all DAC channels?

Simultaneous updates can be achieved using the asynchronous LDAC hardware pin or via the software 'LDAC' command, which transfers contents from input registers to DAC registers at once.

What is the function of the UPO pin?

The User-Programmable Output (UPO) pin acts as a logic output extender, allowing control of external devices across isolated interfaces, such as amplifier gain control.

Can the MAX534 be daisy-chained?

Yes, the DOUT pin allows daisy-chaining. By using the NOP instruction, data can pass through intermediate devices without altering their internal states.
