Description

CNVST

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 (t8) is complete, the internal sample-and-hold is put into the hold state and a conversion is

immediately started.

REF

This input pin is used to provide a reference to the converter.

REFGND

Reference Input Analog Ground.

39, 41

INB1, INB2

Channel B Analog Inputs.

40, 45

INBN, INAN

Analog Inputs Ground Senses. Allow to sense each channel ground independently.

42, 43

REFB, REFA

These inputs are the references applied to Channel A and Channel B, respectively.

44, 46

INA2, INA1

Channel A Analog Inputs.

1 AI = analog input; DI = digital input; DI/O = bidirectional digital; DO = digital output; P = power.
