Analog Input range : 0V to Vref.
Operating modes : One shot and Repeat modes.
Sample and Hold circuits : Available.
Conversion time : Minimum 2.8µSec at 10MHz.
Input channels : Depends on the device. Varying from 4 to 20.
The A/D circuit has the software control to disconnect the Vref voltage from the
converter circuit to reduce the power consumption. Also there is a facility to control
A/D conversion rate by selecting different operating clocks. The sample and hold
circuit can be included in the A/D converter under software control. When the
sample and hold circuit is enabled, the conversion time is reduced to 33 A/D
clock cycles for 10 bits and 28 A/D clock cycles for 8 bits.
