DAC108S085 10-Bit Micro Power OCTAL Digital-to-Analog Converter with Rail-to-Rail Outputs www.DataSheet4U.com October 2007 DAC108S085 10-Bit Micro Power OCTAL Digital-to-Analog Converter with Rail-to-Rail Outputs General Description The DAC108S085 is a full-featured, general purpose OCTAL 10-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to +5.5V supply and consumes 1.95 mW at 3V and 4.85 mW at 5V. The DAC108S085 is packaged in a 16-lead LLP package and a 16-lead TSSOP package. The LLP package makes the DAC108S085 the smallest OCTAL DAC in its class. The on-chip output amplifiers allow rail-to-rail output swing and the three wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25 MHz clock rates at supply voltages in the 2.7V to 3.6V range. The serial interface is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. The DAC108S085 also offers daisy chain operation where an unlimited number of DAC108S085s can be updated simultaneously using a single serial interface. There are two references for the DAC108S085. 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. The DAC108S085 has a 16-bit input shift register that controls the mode of operation, the power-down condition, and the...
