SNAS407H August 2007 – April 2015 DAC128S085
The DAC128S085 is a full-featured, general-purpose OCTAL 12-bit voltage-output digital-to-analog converter (DAC) that can operate from a single 2.7-V to 5.5-V supply and consumes 1.95 mW at 3 V and 4.85 mW at 5 V. The DAC128S085 is packaged in a 16-lead WQFN package and a 16-lead TSSOP package. The WQFN package makes the DAC128S085 the smallest OCTAL DAC in its class. The on-chip output amplifiers allow rail-to-rail output swing, and the 3-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 2.7-V to 3.6-V 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 DAC128S085s 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 0.5 V and VA, providing the widest possible output dynamic range. The DAC128S085 has a 16-bit input shift register that controls the mode of operation, the power-down condition, and the register/output value of the DAC channels. All eight DAC outputs can be updated simultaneously or individually.
