The DAC128S085CIMT is a full-featured general-purpose octal 12-bit voltage-output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and consumes 1.95mW at 3V and 4.85mW at 5V. The on-chip output amplifiers allow rail-to-rail output swing and the 3-wire serial interface operates at clock rates up to 40MHz over the entire supply voltage range. Competitive devices are limited to 25MHz clock rates at supply voltages in the 2.7 to 3.6V range. The serial interface is compatible with standard SPI?, QSPI, MICROWIRE and DSP interfaces. The DAC128S085 also offers daisy-chain operation, where an unlimited number of DAC128S085 can be updated simultaneously using a single serial interface. There are two references for the DAC128S085. One reference input serves channels A through D, while the other reference serves channels E through H. Each reference can be set independently between 0.5V and VA, providing the widest possible output dynamic range.
