Azoteq IQS9320 ProxFusion® IC
Azoteq IQS9320 ProxFusion® IC is a flexible multi-channel inductive sensing device. This IC supports a high number of channels per device, adjustable trigger points, analog data streaming, and high report rates. The trigger-level UI allows for adjustable trigger point sensitivity, resulting in a better user experience with class sensitivity and power consumption. This IC operates from 2.2V to 3.5V input supply voltage range and -40°C to 85°C temperature range. The IQS9320 IC features automatic channel calibration, TriggerMax™ dynamic trigger point adjustment, environmental tracking, multi-device matrix key scanning, and synchronized sampling. Typical applications include mechanical keyboards, waterproof buttons (inductive), remote controls, and gaming controllers.
