What is the Effective Resolution of 7135 ADC
The resolution if you 'and' with the externally supplied ADC clock is 1 count or 1 in 20,000. If the external clock was synchronized with a microcontroller timing peripheral you could conceivably do better, but it will be limited by the noise floor, which is typically 15uV-30uV to two sigmas, so it's conceivable to get to a typical resolution of 1 part in 50,000 (about 15-16bits).
