AD5684R
nanoDAC+TM是一款四通道、12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。
It is powered from a single 2.7 V to 5.5 V supply and is designed to ensure monotonicity, with an FSR gain error of less than 0.1% and an offset error of 1.5mV. Available in 3mm x 3mm LFCSP and TSSOP packages.
AD5684R also has a built-in power-on reset circuit and an RSTSEL pin to ensure that the DAC output is powered up to zero or mid-range until a valid write operation is performed. With independent power-saving features for each channel, the device's power consumption at 3 V is reduced to 4 uA in power-saving mode.
AD5684R features a versatile SPI interface with clock rates up to 50 MHz and includes a VLOGIC pin for 1.8V/3V/5V logic levels.
