mTouch AR1100 analog resistive USB touch-screen controller

The mTouch AR1100 analog resistive USB touch-screen controller is a plug-and-play device that offers advanced calibration capabilities as a USB mouse or single-input digitiser.

The controller is available as a turnkey chip or board product, supporting all 4-/5-/8-wire touch screens, with free drivers for most major operating systems. It is suitable for users who want a drop-in touch controller to universally support their entire standard resistive-touch portfolio.

The controller features calibration options for alignment and linearisation, enabling good accuracy for four-, five- and eight-wire touch screens, as well as highly accurate button pressing for applications with tight spacing.

In addition to the controller, the company has announced enhancements to its AR1000 analog resistive touch-screen controllers, a full suite of drivers including those for the Windows CE, Linux and Android operating systems and a new minimum operating voltage, down to 2.0. It is a turnkey analog resistive touch controller that targets low-cost embedded applications using I₂C, SPI or UART communications.
