The DAC128S085EB features one of the members from our family of OCTAL 8-, 10-, and 12-bit general purpose Digital-to-Analog Converters (DACs) with Rail-to-Rail Output. Enclosed is the evaluation kit for this product, including the DAC128S085 evaluation board and a user's guide for this board. The DAC128S085EB can be evaluated in manual or computer mode. In manual mode, a pattern generator is used to interface with the board. In order to interface this board to a PC, a WaveVision (WV) Data Capture Board, version 4.1 or higher, is required. The WV Data Capture Board requires WaveVision software version 4.4 or higher for the DAC128S085EB to be recognized automatically by the WV software.
The DACXX8S085 family of DACs features an SPI interface with daisy chain capability that operates at clock rates up to 40 MHz. The supply voltage can range from +2.7V to +5.5V and consumes just 1.95 mW at 3V and 4.9 mW at 5V. A power-down feature where individual channels can be powered down independently reduces the power consumption of all family members to 0.3 uW at 3V and 1.0 uW at 5V. The DACXX8S085 family features two external reference inputs that supply the reference voltage for channels A to D and channels E to H. The references for the family of DACs can vary in voltage between 0.5V and VA.
