AD5686/AD5684 is a 16/12-bit nanoDAC+ with SPI interface. It features high relative accuracy (INL), small size, high drive capability, low power consumption, and high ESD protection.
The AD5686/AD5684 are members of the nanoDAC+ family, serving as low-power, quad, buffered voltage output digital-to-analog converters (DACs). The devices offer high relative accuracy with a maximum integral nonlinearity (INL) of +2 LSB for the 16-bit AD5686 and +1 LSB for the 12-bit AD5684. They feature a total unadjusted error (TUE) of +0.1% of full-scale range (FSR) maximum.
