Description
Start Conversion. A falling edge on CNVST puts the internal sample-and-hold into the hold state and
initiates a conversion. In impulse mode (IMPULSE = HIGH), if CNVST is held LOW when the acquisition
phase (t
immediately started.
This input pin is used to provide a reference to the converter.
Reference Input Analog Ground.
Channel B Analog Inputs.
Analog Inputs Ground Senses. Allow to sense each channel ground independently.
These inputs are the references applied to Channel A and Channel B, respectively.
Channel A Analog Inputs.
