Product Overview
AD7147 CapTouch™ controller is designed for use with capacitance sensor implementing functions such as buttons, scroll bars, and wheels. The sensors need only one PCB layer, enabling ultrathin applications. This is an integrated CDC with on-chip environmental calibration. The CDC is capable of sensing changes in the capacitance of the external sensors and uses this information to register a sensor activation. By programming the registers, the user has full control over the CDC setup. High resolution sensors require minor software to run on the host processor. This is designed for single electrode capacitance sensors (grounded sensors). There is an active shield output to minimize noise pickup in the sensor. It has on-chip calibration logic to compensate for changes in the ambient environment. Application includes cell phones, personal music and multimedia players, smart handheld devices, television, A/V, and remote controls, gaming consoles, digital still cameras.
- Programmable capacitance-to-digital converter (CDC), femtofarad resolution
- Wake up on proximity, SPI interface
- Automatic conversion sequencer, on-chip automatic calibration logic
- Automatic compensation for environmental changes
- Automatic adaptive threshold and sensitivity levels
- On-chip RAM to store calibration data, SPI-compatible serial interface
- Separate VDRIVE level for serial interface, interrupt output and general-purpose input/output (GPIO)
- Resolution is 16bits (typ, VCC = 2.6V to 3.6V, TA = -40 to +85°C)
- 24 lead LFCSP-WQ package, operating temperature range from -40°C to +85°C
