6. Module: 10-bit ADC: Sampling Rate
The maximum sampling rate for the 10-bit
Analog-to-Digital Conversion module is 750 ksps.
This rate is only achievable when one A/D pin is
being used. Configuring the ADC module to use
multiple sample-and-hold circuits (see device data
sheet), will not improve the conversion speed of
the module.
Table 1 shows the maximum ADC conversion
rates possible using the 10-bit ADC module and
the corresponding module configuration and
operating conditions.
Work around
None.
