The ADS7845E/2K5G4 is an 8-bit, 8-channel A/D converter designed to be an ideal component in a human-machine interface, providing exceptional flexibility when used in touch screen interfaces. This part distinguishes itself from other A/D converters with its advanced features, low power consumption, and low cost. The ADS7845E/2K5G4 offers unprecedented performance and reliable operation in a number of applications including consumer electronics, industrial control, medical equipment and data acquisition systems.

The ADS7845E/2K5G4 provides an 8-bit resolution and an impressive signal-to-noise ratio (SNR) of 80 dB, making it suitable for many demanding applications. It also has built-in sample and hold (S&H) and signal conditioning that enable method and accurate data capture. The device offers two different signal-to-noise ratios: one for low-frequency signals, which can be as low as 46 dB, and the other for high-frequency signals, which can be as high as 80 dB. This range of signal-to-noise ratios allows the ADS7845E/2K5G4 to be used in a wide range of data acquisition applications.

The ADS7845E/2K5G4 has several features that enhance its usefulness in touch screen applications such as DC-coupled and AC-coupled modes, low power mode, and thermal shutdown. The low power mode enables the device to reduce its overall power consumption when not actively performing conversion operations, which makes it ideal for battery-powered applications. The device also has an internal temperature sensor which allows it to trigger a thermal shutdown when the internal temperature gets too high to protect the device from overheating.

The ADS7845E/2K5G4 has an advanced working principle that allows the device to sense and react to a wide range of signals, from the momentary touches of the human finger to a constant force applied to a touch screen. In order to achieve this, the converter’s sensing elements are embedded within a conductive microgrid which can sense the strength of applied signals. The microgrid divides the area into thousands of individual squares and distributes thoseelectromotive forces over the entire surface of the device, which is analogous to the way a hand can feel the force applied to a Christmas tree bulb.

In addition, the ADS7845E/2K5G4 also has two different output modes that can be used depending on the application. The first output mode provides a single output channel for a single input voltage, and the second output mode provides an individual channel for each change in the applied input voltage. This allows for greater accuracy and flexibility when capturing or processing the data from touch screens.

The ADS7845E/2K5G4 is an ideal component for applications such as industrial control, medical equipment, and data acquisition. It is a highly reliable and low cost A/D converter available in an 8-bit resolution. Its advanced features and low power consumption make it an ideal choice for touch screen applications. With its various output modes and high SNR, this converter can be used to provide excellent data acquisition in a wide range of applications.
