SX9306数据手册集成电路（IC）的传感器电容式触控规格书PDF

描述 Description

The SX9306 is an ultra-low power capacitive Specific Absorption Rate (SAR) controller that accurately discriminates between an inanimate object and human body proximity. The resulting detection is used in portable electronic devices to reduce and control radio-frequency (RF) emission power in the presence of a human body, enabling significant performance advantages for manufacturers of electronic devices with electro-magnetic radiation sources to meet stringent emission regulations'criteria and Specific Absorption Rate (SAR) standards. Operating directly from an input supply voltage of 2.7 to 5.5V, the SX9306 outputs its data via a 1.65 – 5.5V host compatible I2C serial bus.
