13.1 Introduction
The ADC12B16C is a 16-channel, 12-bit, multiplexed input successive approximation analog-to-digital
converter. Refer to device electrical specifications for ATD accuracy.
13.1.1 Features
• 8-, 10-, or 12-bit resolution.
• Conversion in Stop Mode using internally generated clock
• Automatic return to low power after conversion sequence
• Automatic compare with interrupt for higher than or less/equal than programmable value
• Programmable sample time.
• Left/right justified result data.
• External trigger control.
• Sequence complete interrupt.
• Analog input multiplexer for 16 analog input channels.
• Special conversions for V_RH, V_RL, (V_RL+V_RH)/2.
• 1-to-16 conversion sequence lengths.
• Continuous conversion mode.
• Multiple channel scans.
• Configurable external trigger functionality on any AD channel or any of four additional trigger
inputs. The four additional trigger inputs can be chip external or internal. Refer to device
specification for availability and connectivity.
• Configurable location for channel wrap around (when converting multiple channels in a sequence).
