MAX5236:Single-Supply 3V/5V, Voltage-Output, Dual, Precision 10-Bit DACs

Industry's Smallest and Most Accurate Dual 10-Bit DACs

The MAX5236/MAX5237 precision, dual, voltage-output, 10-bit digital-to-analog converters (DACs) consume only 360µA from a single 5V (MAX5237) or 325µA from a single 3V (MAX5236) supply. These devices feature output buffers that swing rail-to-rail. The internal gain amplifiers (1.6384V/V) maximize the dynamic range of the DAC output. The MAX5236/MAX5237 feature 13.5MHz a 3-wire serial interface compatible with SPI™/QSPI™/and MICROWIRE™. Each DAC input is organized as an input register followed by a DAC register. A 16-bit shift register loads data into the input registers. Input registers update the DAC registers independently or simultaneously. In addition, programmable control bits allow power-down with 1kΩ or 200kΩ internal loads. The MAX5236/MAX5237 are fully specified over the extended industrial temperature range (-40°C to +85°C) and are available in space-saving 10-pin µMAX® packages.
