Overview
This xCHIP forms part of the sensor modules, used for digital signal acquisition.
The converter is based on a successive approximation register architecture with an internal track-
and-hold circuit that can handle input frequencies up to 11MHz. The ADC081C021 operates from a
single supply which also serves as the reference. The device features an I
2
C-compatible serial
interface that operates in all three speed modes, including high speed mode (3.4MHz). The ADC's
Alert feature provides an interrupt that is activated when the analog input violates a programmable
upper or lower limit value. The device features an automatic conversion mode, which frees up the
controller and I
2
C interface. In this mode, the ADC continuously monitors the analog input for an
"out-of-range" condition and provides an interrupt if the measured voltage goes out-of-range.
