Missing-codes tester checks 16-bit ADC in 7 sec


Posted on Sep 13, 2012

As the resolution of ADCs increases from 12 to 16 bits and higher, the difficulty in testing the `no- missing-codes` specification grows proportionately. To fully guarantee no missing codes for a 16-bit ADC requires testing all 2161 possible output codes. Undertaking such a production test could add much extra cost to the ADC without a quick method for testing all codes. Fortunately, a simple approach can test the no-missing-codes specification for a 16-bit ADCin this case, a 10-µsec ADS7805, in typically less than 7 sec (Figure 1).
