A/D (Analog-to-Digital) Module
There now exists several different versions of the A/D module in Microchip’s design library. The
first A/D module (now called Basic 8-bit A/D) is an 8-bit A/D with four input channels. The second
A/D module (called 8-bit A/D) is an 8-bit A/D with up to 8 input channels. The Third A/D module
(called 10-bit A/D) is a 10-bit A/D with up to16 input channels implemented.
which devices have an A/D module, and the version implemented. As new devices are intro-
duced, either the 8-bit A/D module or 10-bit A/D module will be implemented (that is the Basic
8-bit A/D module is being phased out). If your application requires the 10-bit A/D, you should refer
to Microchip’s High End Family (PIC17CXXX). This family currently has some devices that have
this module implemented.
