SX9324 Datasheet (Semtech) - Smart Proximity Sensor

SX9324, Smart Proximity Sensor

The SX9324 is a capacitive Specific Absorption Rate (SAR) controller.

The SX9324 can use two sensor inputs coupled to its smart engine for SAR to accurately discriminate between an inanimate object and human body.

The resulting detection is used in portable electronic devices to reduce and control r
