The MAX5234/MAX5235 precision, dual-output, 12-bit digital-to-analog converters (DACs) consume only 360µA from a single 5V (MAX5235) or 325µA from a single 3V (MAX5234) supply. These devices feature output buffers that swing rail-to-rail. The internal gain amplifiers maximize the dynamic range of the DAC output.
The MAX5234/MAX5235 feature a 13.5MHz 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 MAX5234/MAX5235 are fully specified over the extended industrial temperature range (-40°C to +85°C) and are available in space-saving 10-pin µMAX packages.
