AD5685R
nanoDAC+
TM是一款四通道、14位、轨到轨、电压输出DAC。该器件包含一个2.5V、2ppm/˚C内部基准电压源(默认开启)和一个增益选择引脚,提供2.5V(增益=1)或5V(增益=2)的满量程输出。
Operating from a single 2.7 V to 5.5 V supply, monotonicity is guaranteed by design, with less than 0.1% FSR gain error and 1.5 mV offset error. Available in 3mm x 3mm LFCSP and TSSOP packages.
AD5685R还内置一个上电复位电路和一个RSTSEL引脚,确保DAC输出上电至零电平或中量程,直到执行一次有效的写操作为止。具有各通道独立省电特性,在省电模式下,器件在3 V时的功耗降至4 uA。
AD5685R采用多功能SPI接口,时钟速率最高达50 MHz,包含一个为1.8V/3V/5V逻辑电平准备的VLOGIC引脚。
