CAV414 Overview
The CAV414 is an universal multipurpose interface for capacitive sensors and contains the plete signal processing unit on chip. The CAV414 detects the relative capacitive change of a measuring capacity to a fixed reference capacity. The IC is optimised for capacities in the wide range of 10pF to 2nF with possible changes of capacity of 5% to 100% of the reference capacity.
