Amey,

   The ADCON0 register is for conversion time.  You are asking about
sampling time. At 16kHz you would need to take an A/D reading every 62.5
microseconds.  This is well within the settling time of the 16c71s A/D
module.  Use a timer interrupt set at your sampling rate to start the A/D
conversion and then use the A/D interrupt to read the answer after the
conversion is complete.  Once the conversion is completed the channel will
begin to recharge its internal RC circuit again after 2Tad which will still
give you plenty of time for the reading to settle before your next sampling
point.
