January 23, 2014

Azoteq’s IQS333 is the first capacitive touch controller with precision 11-bit scroll wheels or sliders and 8-channel PWM LED driver.

Austin, TX (PRWEB) January 23, 2014

Azoteq, the world leader in proximity and touch solutions, today announced the release to market of the IQS333. The IQS333 is the first capacitive touch and proximity controller that offers two 11-bit scroll wheel or sliders. Competitive capacitive controllers typically only offer 8-bit resolution that not fine enough for applications such as instrumentation, audio equipment and appliances.

The IQS333 offers 7 self-capacitance or 9 mutual-capacitance channels. Proximity wakeup allows very low power consumption until the user interacts with the product. The IQS333 also 8 PWM LED drivers to implement fade in/out backlights. The PWM dimming does not require any overhead from the host controller.

“The IQS333 is the first capacitive controller to offer two precision 11-bit scroll wheels or sliders in a single package. With the integrated 8-channel PWM LED driver the IQS333 can be used to implement a complete user interface,” said Kobus Marneweck, VP of Marketing.
