Analog-to-Digital Converter (ATD10B8CV3)
7.1 Introduction
The ATD10B8C is an 8-channel, 10-bit, multiplexed input successive approximation analog-to-digital
converter. Refer to device electrical specifications for ATD accuracy.
7.1.1 Features
• 8/10-bit resolution
• 7 µsec, 10-bit single conversion time
• Sample buffer amplifier
• Programmable sample time
• Left/right justified, signed/unsigned result data
• External trigger control
• Conversion completion interrupt generation
• Analog input multiplexer for 8 analog input channels
• Analog/digital input pin multiplexing
• 1-to-8 conversion sequence lengths
• Continuous conversion mode
• Multiple channel scans
• Configurable external trigger functionality on any AD channel or any of four additional external
trigger inputs. The four additional trigger inputs can be chip external or internal. Refer to the device
overview chapter for availability and connectivity.
• Configurable location for channel wrap around (when converting multiple channels in a sequence).
7.1.2 Modes of Operation
7.1.2.1 Conversion Modes
There is software programmable selection between performing single or continuous conversion on a single
channel or multiple channels.
