AD7147ACPZ-500RL7

AD7147 CapTouch™ programmable controller is designed for use with capacitance sensors implementing functions such as buttons, scroll bars and wheels. The sensors need only one PCB layer, enabling ultrathin applications. AD7147 is designed for single electrode capacitance sensors (grounded sensors). There is an active shield output to minimize noise pickup in the sensor. Typical applications include cell phones, personal music and multimedia players, smart handheld devices, Television, A/V and remote controls, gaming consoles, digital still cameras.
