8.3 A/D CONVERTER (ADC)

8.3.1 Introduction

The on-chip Analog to Digital Converter (ADC) pe-

ripheral is a 8-bit, successive approximation con-

verter. This peripheral has multiplexed analog in-

put channels (refer to device pin out description)

that allow the peripheral to convert the analog volt-

age levels from different sources.

The result of the conversion is stored in a 8-bit

Data Register. The A/D converter is controlled

through a Control Register.

8.3.2 Main Features

8-bit conversion

Multiplexed analog input channels

Linear successive approximation

Data register (DR) which contains the results

End of Conversion flag

On/Off bit (to reduce consumption)

Typical conversion time 70 µs (with an 8 MHz

crystal)

The block diagram is shown in Figure 34.
