The MAX11801ETC+T is an integrated touch-screen controller that combines a 324-channel sensor scanning, 8-bit internal resolution, X/Y position determination and signal conditioning in a single device. This device is categorized as Data Acquisition – Touch Screen Controllers based on its application and purpose.

The MAX11801ETC+T enables a robust solution by combining a complete touch-screen controller solution with touch-screen transducer drive. It is ideal for cost-sensitive and space-constrained applications while meeting the highest performance and reliability standards. In addition, it can be used with any popular touch-screen transducer type, including analog resistive, projected capacitive and impedance. Additionally, the MAX11801ETC+T can support a wide range of screen sizes, from small portable products to large industrial displays.

The operating principle of the MAX11801ETC+T is based on a charge-transfer technology sampling system. Oscillators generate sawtooth-shaped reference waveforms for the sense X and sense Y electrodes. When an external transducer is connected to the device, these references are transferred to the V-VOLTAGE or V-COM signals from the capacitive sensors. The absolute values of these signals are registered to the internal counters, providing X and Y coordinate information.

The MAX11801ETC+T also has high resolution sampling that ensures a more accurate detection of touch events. This device can detect up to 324 separate channels, including 128 channels in its X-axis, 128 channels in Y-axis and 8 redundant channels for each axis for better noise margin. The MAX11801ETC+T also has an advanced filtering algorithm that improves the noise immunity and reduces the interference from cheap light or shadows.

In addition to its excellent performance, the MAX11801ETC+T also features lower system power consumption and low EMI/RFI radiation. It is capable of both static and dynamic power saving through its ultra-low power design, ensuring a longer battery life for handheld and portable devices. Additionally, the device has a low EMI/RFI radiation, avoiding interference with other nearby systems.

The MAX11801ETC+T is widely used in applications such as consumer PADs and tablets, automotive infotainment systems, medical monitors, industrial and legal scales, lottery machines and point-of-sale terminals. These application fields require a high level of accuracy and reliability and the MAX11801ETC+T is an ideal solution for these applications.

Overall, the MAX11801ETC+T is a versatile and reliable touch-screen controller that is suitable for a wide range of applications. Its wide range of features makes it an ideal choice for any high-performance and cost-sensitive touch-screen performance requirement.
