Analog-to-Digital Converter (ATD10B16CV2)
6.1 Introduction
The ATD10B16C is a 16-channel, 10-bit, multiplexed input successive approximation analog-to-digital
converter. Refer to the Electrical Speciï¬cations chapter for ATD accuracy.
6.1.1 Features
⢠8-/10-bit resolution
⢠7 µs, 10-bit single conversion time
⢠Sample buffer ampliï¬er
⢠Programmable sample time
⢠Left/right justiï¬ed, signed/unsigned result data
⢠External trigger control
⢠Conversion completion interrupt generation
⢠Analog input multiplexer for 16 analog input channels
⢠Analog/digital input pin multiplexing
⢠1 to 16 conversion sequence lengths
⢠Continuous conversion mode
⢠Multiple channel scans
6.1.2 Modes of Operation
There is software programmable selection between performing single or continuous conversion on a
single channel or multiple channels.
6.1.3 Block Diagram
Refer to Figure 6-1 for a block diagram of the ATD0B16C block.
