EVAL-AD5697RSDZ

双通道， 12位属于nanoDAC与2 PPM / A ° C参考， I2C接口 Dual, 12-Bit nanoDAC with 2 ppm/°C Reference, I2C Interface

The is an evaluation kit designed to help customers quickly prototype new AD5697R circuits and reduce design time. The AD5697R is a dual, 12bit, voltage output DACs. The device includes 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 AD5697R operates from a single 2.7V to 5.5V supply. The part incorporates an internal 2.5V on board reference to give an output voltage span of 2.5V or 5V. The onchip 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 AD5697R. The software has a simulation mode option to mimic the operation of the DAC without the use of the evaluation board.
