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.
