The SAA-XC866 includes a high-performance 10-bit Analog-to-Digital Converter (ADC)
with eight multiplexed analog input channels. The ADC uses a successive approximation
technique to convert the analog voltage levels from up to eight different sources. The
analog input channels of the ADC are available at Port 2.
Features:
• Successive approximation
• 8-bit or 10-bit resolution
• Eight analog channels
• Four independent result registers
• Result data protection for slow CPU access
• Single conversion mode
• Autoscan functionality
• Limit checking for conversion results
• Data reduction filter
• Two independent conversion request sources with programmable priority
• Selectable conversion request trigger
• Flexible interrupt generation with configurable service nodes
• Programmable sample time
• Programmable clock divider
• Cancel/restart feature for running conversions
• Integrated sample and hold circuitry
• Compensation of offset errors
• Low power modes
