Analog-to-Digital Converter (ADC)
28.1 Introduction
NOTE
For the chip-specific implementation details of this module's
instances see the chip configuration information.
The 16-bit analog-to-digital converter (ADC) is a successive approximation ADC
designed for operation within an integrated microcontroller system-on-chip.
NOTE
For the chip specific modes of operation, see the power
management information of the device.
28.1.1 Features
Features of the ADC module include:
• Linear successive approximation algorithm with up to 16-bit resolution
• Up to four pairs of differential and 24 single-ended external analog inputs
• Output modes:
• differential 16-bit, 13-bit, 11-bit, and 9-bit modes
• single-ended 16-bit, 12-bit, 10-bit, and 8-bit modes
• Output format in 2's complement 16-bit sign extended for differential modes
• Output in right-justified unsigned format for single-ended
• Single or continuous conversion, that is, automatic return to idle after single
conversion
