MAX5721EUA+T

Digital To Analog Converters Overview

The MAX5721EUA+T is a dual 10-bit, low-power, buffered voltage-output digital-to-analog converter (DAC) housed in an 8-pin µMAX package. It operates on a single supply voltage ranging from +2.7V to +5.5V with a typical supply current of 112µA at +3.6V and 135µA at +5.5V. The device features rail-to-rail output buffer amplifiers and accepts a reference input voltage from 0 to VDD. It supports a 20MHz serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols. The part includes a power-on reset circuit that initializes outputs to zero and provides software-selectable power-down modes reducing current to less than 0.3µA. It is specified for operation over the -40°C to +125°C temperature range.

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Ensure the ordering suffix matches the required temperature range (+85°C for 'E' suffix). Confirm the package type is 8-pin µMAX. Check for RoHS compliance status as indicated in the product documentation. Validate the revision level of the datasheet to ensure compatibility with design requirements.

Digital To Analog Converters Selection Notes

Select the MAX5721EUA+T when a dual-channel, low-power DAC is required for battery-operated or portable applications. Consider this component if system constraints demand a small footprint provided by the 8-pin µMAX package. Verify that the required serial interface protocol (SPI/QSPI/MICROWIRE) is supported by the host microcontroller. Ensure the application can accommodate the specified supply voltage range and temperature extremes.

Digital To Analog Converters Part Context

The MAX5721 belongs to Maxim Integrated's family of low-power digital-to-analog converters. It is designed for applications requiring precise analog signal generation with minimal power consumption.
