Azoteq IQS7211A ProxFusion Combination Sensors

Azoteq’s smallest trackpad controller ever

The Azoteq IQS7211A is part of the manufacturer's latest range of ProxFusion combination sensors. The chip allows users to control a trackpad of up to 32-channels. The IQS7211A IC is designed for the wearable and hearable markets based on its low power consumption, small package size and long term activation supported by environmental tracking.

What is ProxFusion®?

ProxFusion® multi-sensor technology is an innovative product line by Azoteq offering combinations of capacitive sensing, Hall-effect, inductive and temperature sensing on a single IC. With the approach of having multiple sensors embedded on a single sensor IC, ProxFusion® will reduce the bill of materials, reduce power consumption, improve reliability, reduce board space, reduce the number of interface pins to the host CPU and bring major cost reductions to the final product.
