IQS327
The IQS327 ProxFusion® IC is a sensor fusion device for multi-level analogue sensing. An additional capacitive channels can be used in tandem to increase the reliability and accuracy of the multi-level inductive trigger solution. The sensor is fully I2C compatible and on-chip calculations enable the IC to respond effectively even in lowest power modes.
