Azoteq Announces IQS259 Ultra Low Power Capacitive Proximity and Touch Controller

Azoteq, the world leader in capacitive proximity solutions, today announced the release to market of the IQS259. The IQS259 is Azoteq’s latest addition to the ProxSense® family of capacitive proximity and touch controllers. The IQS259 sets new standards for proximity and touch sensing with power consumption of 8 microampere, which is up to 100 times better than competitive devices.

The IQS259 uses advanced analog and digital circuitry to achieve unparalleled proximity and touch performance. The high sensitivity enables the IQS259 to work reliably through glass up to 25 mm thick and achieves proximity detection up to 250 mm. The device can operate from 1.8 to 3.6V and achieves power consumption as low as 8 microampere while still sensing proximity and touch. The I2C-compatible interface allows for full control of the sensor functions from a host controller.

“Azoteq provides the only proximity and touch solutions that enable designers to achieve first-time success with their design due to the auto-tuning and drift compensation features,” said Kobus Marneweck, VP of Marketing at Azoteq. “These features also dramatically increase the manufacturability of the product by compensating for any changes in the environment,” he added.

Azoteq is releasing a full family of controllers based on the IQS259 technology during Q1 and Q2 of 2012. The expanding feature sets include stand-alone devices, self- and mutual capacitive sensors and lower cost single-channel devices in small packages.
