EVAL-AD5689RSDZ

双通道， 16位/ 12位属于nanoDAC与2 PPM / A ° C参考， SPI接口 Dual, 16-/12-Bit nanoDAC with 2 ppm/°C Reference, SPI Interface

The is an evaluation kit designed to help customers quickly prototype AD5689R circuit and reduce design time. The AD5689R include a 2.5V, 2ppm/°C internal reference enabled by default and a gain select pin giving a full scale output of 2.5V gain = 1 or 5V gain = 2. The AD5689R also incorporate a power on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. The AD5689R operates from a single 2.7V to 5.5V supply. The part incorporates an internal 2.5V onboard reference to give an output voltage span of 2.5V or 5V. The onboard reference is on at power up. The part must be written to after power up to turn off the internal reference. The evaluation board interfaces to the USB port of an IBM compatible PC via the SDP board. Software is available with the evaluation board which allows the user to easily program the AD5689R and simulation mode is available.
