Testing Multi-Stage DACs: A Practical Approach

“When testing the Integral Non-Linearity (INL) and Differential Non-Linearity (DNL) of multi-stage DACs, it is usually unnecessary to perform a full test on all codes. Instead, validation can be achieved by carefully selecting a subset of key codes.” For example: a 16-bit 3-stage DAC, which internally contains 3 sub-DACs (7-bit, 5-bit, 4-bit), requires scanning all … Read more
