Azoteq Announces the IQS680, a Multi Functional Capacitance, Passive Infrared (PIR) and Inductance Sensor
16th May, 2018

AUSTIN, Texas - May 15, 2018 - Azoteq, a pioneer in sensor fusion, today announced the release to market of the IQS680. The IQS680 ProxFusion® IC is a multifunctional capacitance, Passive Infrared (PIR) and inductance sensor designed for applications such as domestic energy-efficient lighting applications with movement detection. The IQS680 is a standalone ultra-low-power solution designed for short- or long-term activations through any of the sensing channels.

The IQS680 combines up to three sensing technologies into a single, integrated ASIC. Two of the three sensing technologies can be used simultaneously. The IQS680 omits the need for the conventional, high BOM count, low-noise amplifier circuit for the PIR sensor. Signal processing is performed on-chip, along with either an inductive or capacitive-sensing channel for an enhanced user interface and control.

The ProxFusion® family builds on Azoteq s decade of capacitive-sensing experience and adds unique sensing capabilities in single-chip solutions.

“The IQS680 is a big step forward in PIR-controlled lighting applications,” said Jean Viljoen, Azoteq s VP of Marketing. “All amplifier and sensing circuitry are performed in a single ASIC, while the inductive and capacitive channels allow for additional human or mechanical control of the light source.”

Samples, production quantities and evaluation kits are available through Azoteq s distribution channels and popular online distributors.
