The MAX5234/MAX5235 precision, dual-output, 12-bit digital-to-analog converters (DACs) consume only 360A from a single 5V (MAX5235) or 325A 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 SPITM, QSPITM, and MICROWIRETM. 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 1k or 200k internal loads.
