IQS156 Datasheet
IQ Switch® - ProxSense® Series
Minimalist Capacitive Sensor with Compensation for Sensitivity Reducing Objects
Unparalleled Features
Sub 6uA current consumption
Automatic tuning for optimal operation in various environments
The IQS156 ProxSense® IC is a fully integrated six channel capacitive contact and proximity
sensor with market leading sensitivity and automatic tuning to the sense electrodes. The IQS156
provides a minimalist implementation requiring as few as 2 external components. The device is
ready for use in a large range of applications while programming options allow customisation for
specialized applications.

Forces the Long Term Average to stop being calculated
„0‟: LTA updates normally
„1‟: LTA is halted
Forces the ATI routine to run when a „1‟ is written into this bit
position. ATI OFF in D4 should not be set.
All channels are reseeded when a „1‟ is written into this bit
position. The LTA‟s are set to 8 counts above the counts.
