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 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 8-bit
Data Register. The A/D converter is controlled
through a Control/Status Register.

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 the Electrical character-
istics section.
11.4.3.2 Input Voltage Amplifier
The input voltage can be amplified by a factor of 8
by enabling the AMPSEL bit in the ADAMP regis-
ter.
When the amplifier is enabled, the input range is
0V to 250 mV.
For example, if V

ideal resolution of 2.4mV (equivalent to 11-bit res-

For more details, refer to the Electrical character-
istics section.
Note: The amplifier is switched on by the ADON
bit in the ADCCSR register, so no additional start-
up time is required when the amplifier is selected
by the AMPSEL bit.
