MAX5591AEUI+

Digital To Analog Converters Overview

The MAX5591AEUI+ is an octal, 12-bit voltage-output digital-to-analog converter (DAC) featuring force-sense-configured output buffers. It operates from a +2.7V to +5.25V analog supply and a separate +1.8V to +5.25V digital supply. The device provides a maximum settling time of 3µs at the 12-bit level in FAST mode, with a typical supply current of 4.8mA. It utilizes a 20MHz 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols. Integral nonlinearity is specified at ±1 LSB (max), and differential nonlinearity is guaranteed monotonic at ±1 LSB (max). The component is housed in a 28-pin TSSOP package and functions within an extended temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific A-grade suffix against the manufacturer's official documentation to confirm linearity specifications. Ensure the ordering code matches the required 28-pin TSSOP package configuration. Confirm RoHS compliance status through the authorized distributor or manufacturer directly. Validate that the power-up state selection pin configuration aligns with system requirements.

Digital To Analog Converters Selection Notes

Select this model when high-speed settling is required alongside multi-channel precision. The force-sense buffer design allows for external feedback connections to adjust gain or perform signal conditioning. Compare against unity-gain variants if external feedback is not needed. Verify that the digital supply voltage range supports the host microcontroller logic levels.

Digital To Analog Converters Part Context

This component belongs to the MAX5590–MAX5595 family of buffered, fast-settling, octal DACs. The MAX5591 variant specifically denotes the 12-bit resolution with force-sense outputs. It shares the same serial interface and pinout structure as other members of the series, differing primarily in resolution and buffer configuration.

Digital To Analog Converters Replacement Considerations

The MAX5591BEUI+ is a documented substitute within the same product family. It offers identical functionality but features B-grade linearity specifications compared to the A-grade performance of the MAX5591AEUI+.
