23.2 Introduction

The 16-bit analog-to-digital converter (ADC) is a successive approximation ADC

designed for operation within an integrated microcontroller system-on-chip.

For the chip specific modes of operation, see the power

management information of the device.

Following are the features of the ADC module.

• 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

• Configurable sample time and conversion speed/power

• Conversion complete/hardware average complete flag and interrupt

• Input clock selectable from up to four sources

• Operation in low-power modes for lower noise

• Asynchronous clock source for lower noise operation with option to output the clock

• Selectable hardware conversion trigger with hardware channel select

• Automatic compare with interrupt for less-than, greater-than or equal-to, within

range, or out-of-range, programmable value
