8-bit Analog-to-Digital Converter (ADC)
9.1
Introduction
The on-chip Analog to Digital Converter (ADC) peripheral is a 8-bit, successive approximation
converter with internal Sample and Hold circuitry. This peripheral has up to 4 multiplexed analog
input channels (refer to device pin out description) that allows the peripheral to convert the analog
voltage levels from up to 4 different sources.
The result of the conversion is stored in a 8-bit Data Register. The A/D converter is controlled
through a Control/Status Register.
9.2
Main Features
8-bit conversion
Up to 4 channels with multiplexed input
Linear successive approximation
Data register (DR) which contains the results
Conversion complete status flag
On/Off bit (to reduce power consumption)
9.3
Functional Description
The high and low level reference voltages are V
DD
and V
SS
, respectively. Consequently, conversion
accuracy is degraded by voltage drops and noise in the event of heavily loaded or badly decoupled
power supply lines.
