10.3 10-BIT A/D CONVERTER (ADC)
10.3.1 Introduction
The on-chip Analog to Digital Converter (ADC) pe-
ripheral is a 10-bit, successive approximation con-
verter with internal sample and hold circuitry. This
peripheral has up to 5 multiplexed analog input
channels (refer to device pin out description) that
allow the peripheral to convert the analog voltage
levels from up to 5 different sources.
The result of the conversion is stored in a 10-bit
Data Register. The A/D converter is controlled
through a Control/Status Register.
10.3.2 Main Features
■ 10-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)
The block diagram is shown in Figure 36.
10.3.3 Functional Description
10.3.3.1 Analog Power Supply
V
DDA and VSSA are the high and low level reference
voltage pins. In some devices (refer to device pin
out description) they are internally connected to
the V
DD and VSS pins.
Conversion accuracy may therefore be impacted
by voltage drops and noise in the event of heavily
loaded or badly decoupled power supply lines.
