The serial interface sends out the conversion results during the 16 clock cycles following a CONV rising edge for compatibility with standard serial interfaces. If two additional clock cycles for acquisition time are allowed after the data stream in between conversions, the full sampling rate of 3.5Msps can be achieved with a 63MHz clock. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
