Chapter 6 Analog-to-Digital Converter (ATD10B16CV2)
6.3.2.16.2
6.4
The ATD10B16C is structured in an analog and a digital sub-block.
6.4.1
The analog sub-block contains all analog electronics required to perform a single conversion. Separate
power supplies V
6.4.1.1
The sample and hold (S/H) machine accepts analog signals from the external world and stores them as
capacitor charge on a storage node.
The sample process uses a two stage approach. During the first stage, the sample amplifier is used to
quickly charge the storage node.The second stage connects the input directly to the storage node to
complete the sample for high accuracy.
When not sampling, the sample and hold machine disables its own clocks. The analog electronics continue
drawing their quiescent current. The power down (ADPU) bit must be set to disable both the digital clocks
and the analog power consumption.
The input analog signals are unipolar and must fall within the potential range of V
