AD7879WACPZ-R5

The AD7879WACPZ-R5 is a touch screen controller that is specifically designed to provide an accurate and reliable input interface to various types of touch screens. It is specially designed to be capable of detecting very small changes in the pressure and tilt of a touch screen, and of providing an ultra-low power solution. This results in it being an ideal choice for a wide number of applications, including in today’s energy-conscious environment.

Components of the AD7879WACPZ-R5

The AD7879WACPZ-R5 consists of three main components – the voltage-to-frequency converter (VF) front-end, the highest-accuracy 3-wire resistive touch screen controller, and a charge-pump-based power management system. The VF front end can measure the force exerted on the touch sensor without being affected by changes in the temperature. The 3-wire resistive touch screen controller is capable of accurately measuring the position and pressure of any type of touch screen, while the charge pump-based power management system helps to ensure lower power consumption.

Features of the AD7879WACPZ-R5

The AD7879WACPZ-R5 is capable of accurately detecting the force, direction and angle of the user’s finger movement, as well as taking into account the varying pressure of different materials. It can detect contact with the touch screen in either a linear or circular form and is also able to accurately detect tilts. In addition, it is capable of achieving high resolutions and low noise levels, with a noise floor of as low as 100Hz, allowing for smooth and accurate operation.

Usage of the AD7879WACPZ-R5

The AD7879WACPZ-R5 is ideal for touch screen applications such as mobile phones, personal digital assistants (PDAs), and tablets. It is also well-suited for laptop and mouse-based gaming, as well as in industrial applications. Additionally, its power management system makes it an ideal choice for applications that require ultra-low power consumption, such as medical device applications, which require frequent battery charging.

Working Principle of the AD7879WACPZ-R5

The AD7879WACPZ-R5 uses a voltage-to-frequency converter (VF) front end to detect the force exerted upon the touch screen. This force is converted into an electrical signal, which is then sent to the touch screen controller. The controller processes this signal to accurately measure the position and pressure of the user’s finger movement. The charge-pump-based power management system helps to ensure that the device is always regulated, enabling long battery life in power-critical applications.

Conclusion

The AD7879WACPZ-R5 is a versatile and reliable touch screen controller that is suitable for a variety of applications. It is capable of detecting very small changes in the forces exerted on the touch screen, while its power management system ensures that power consumption is kept to a minimum. In summary, the AD7879WACPZ-R5 is an excellent choice for any application requiring a reliable and accurate touch screen controller.
