11.4 8-BIT A/D CONVERTER (ADC)
11.4.1 Introduction
The on-chip Analog to Digital Converter (ADC) pe-
ripheral is a 8-bit, successive approximation con-
verter with internal sample and hold circuitry. This
peripheral has up to five multiplexed analog input
channels (refer to device pin out description) that
allow the peripheral to convert the analog voltage
levels from up to five 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.
11.4.2 Main Features
– 8-bit conversion
– Up to 5 channels with multiplexed input
– Linear successive approximation
– Data register (DR) which contains the results
– Conversion complete status flag
– On/off bit (to reduce consumption)
11.4.3 Functional Description
11.4.3.1 Analog Power Supply
The block diagram is shown in Figure 38.
VDD and VSS are the high and low level reference
voltage pins.
Conversion accuracy may therefore be impacted
by voltage drops and noise in the event of heavily
loaded or badly decoupled power supply lines.
For more details, refer to Section 13 ELECTRICAL
