Azoteq IQS243 & IQS904 IQ Switch®
ProxSense® Capacitive Sensors
Azoteq IQS243 & IQS904 IQ Switch® ProxSense® Capacitive Sensors are fully integrated single channel or 3 channel capacitive contact and proximity sensors with market leading sensitivity and automatic tuning to the sense antenna. These sensors each provide a cost effective minimalist implementation requiring very few external components. The IQS243 3 channel capacitive sensor includes an I2C-compatible interface which provides full control to a host. The IQS904 single channel capacitive sensor provides a built-in controller for dimming applications. Azoteq IQS243 & IQS904 IQ Switch® ProxSense® Capacitive Sensors also offer extremely low current consumption, automatic tuning for optimal operation in various environments, and compensation against sensitivity reducing objects.
