MAX5584EUP+T

Digital To Analog Converters Overview

The MAX5584EUP+T is a quad, 8-bit, voltage-output digital-to-analog converter (DAC) in a 20-pin TSSOP package. 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 +5.25V digital supply. It includes a 20MHz, 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols. The unit provides two user-programmable digital I/O ports and glitch-free outputs that power up to zero scale, midscale, or full scale. Integral nonlinearity is ±0.5 LSB maximum.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm lead-free status and RoHS compliance. Confirm the operating temperature range matches the design requirements. Ensure the serial interface timing aligns with the host microcontroller logic levels. Validate the power supply voltages against the absolute maximum ratings.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application. Choose the MAX5584 over higher-resolution variants if cost or speed is prioritized. Verify the need for unity-gain versus force-sense buffer configurations. Consider the available serial protocol compatibility with the system controller.

Digital To Analog Converters Part Context

This part belongs to the MAX5580–MAX5585 family of buffered, fast-settling DACs. The series offers varying resolutions from 8 to 12 bits. The MAX5584 specifically provides 8-bit resolution with unity-gain buffers. Other family members include 10-bit and 12-bit options with different buffer configurations.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the MAX5585EUP+T, which shares the 8-bit resolution but utilizes force-sense output buffers instead of unity-gain. Higher resolution alternatives like the MAX5582EUP+T (10-bit) are available but differ in performance characteristics.
