Digital Feedthrough
Even with CS high, high-speed serial data at any of the digital input or output terminals may couple through the
DAC package internal stray capacitance and appear at the DAC analog output as digital feedthrough. Digital
feedthrough is tested by holding CS high and transmitting 0101010101 from DIN to DOUT.
Analog Feedthrough
Higher frequency analog input signals may couple to the output through internal stray capacitance. Analog
feedthrough is tested by holding CS high, setting the DAC code to all 0s, sweeping the frequency applied to
REFIN, and monitoring the DAC output.
