The Analog-to-Digital Converter (ADC) is an 8-bit successive approximation analog-to-digital
converter with eight analog input channels and four result registers.
It offers two operating modes: scan mode, which sequentially converts the inputs from the
selected set of four input channels, and select mode, which converts the input from a single
input channel.
Figure 10.1 gives a block diagram for the Analog-to-Digital Converter (ADC), which includes
the following components:
Overview
• Resolution: 8 bits
• Eight analog input channels
• Four result registers for holding conversion results
• Operating modes
Block Diagram
- Scan modes: Sequential conversion of the analog inputs from the upper or lower set of
- Select mode: Conversion of the analog input from a single input channel
- Successive approximation analog-to-digital converter, which converts an analog quantity
- Analog input channel selector
- AD Control Registers H, L (ADHCON and ADLCON), which control analog-to-digital
- AD Status Register (ADST), which indicates the completion of a conversion operation
- AD Result Registers 0 to 3 (ADCRn, n=0 - 3), which hold the conversion results
