The AD7147ACPZ-1REEL is an IC (Integrated Circuit) component manufactured by Analog Devices Inc. It is a highly integrated, low-power capacitive touch sensor controller designed for use in various applications such as industrial interfaces, consumer electronics, and automotive systems.
The IC features a 14-bit capacitive-to-digital converter (CDC) that provides accurate touch position sensing on up to 14 different touch-sensitive inputs. With its high-resolution capacitance measurement capability, it ensures precise touch detection and eliminates the need for additional signal conditioning circuitry.
The AD7147ACPZ-1REEL incorporates an automatic calibration feature that compensates for variations in the environmental conditions and maintains optimal touch sensitivity. It also offers built-in self and random calibrations, reducing the need for manual calibration during operation.
To facilitate system integration, the component is equipped with an I2C serial interface, enabling easy communication with host microcontrollers and other devices. It operates at a low supply voltage (from 2.6V to 3.6V) and consumes minimal power, making it suitable for battery-powered applications.
Key features of the AD7147ACPZ-1REEL include its ability to detect both proximity and touch simultaneously, allowing for multi-touch functionality. It also supports proximity sensing of objects without physical contact, offering flexibility for various user interfaces
