Touch Evaluation System (TEVS) for the MAX11811

Active: In Production.

The MAX11811 touch evaluation system (TEVS) demonstrates the rich features of the MAX11811 touch-screen controller (TSC) and allows its evaluation. The TEVS consists of a USB interface board (UTIBB+), MAX11811 evaluation kit (EV kit), and a 4-wire touch sensor mounted with an linear resonant actuator (LRA) motor (USB cable included).

The device is a complete resistive touch-sensor controller solution that targets touch-enabled devices with small- to medium-size displays. The device enables miniaturization of consumer products due to its ultra-small size. Its low power consumption makes it attractive for portable devices.

The TEVS with haptics operates directly from the USB power. Windows XP® and Windows® 7-compatible software running on a PC interfaces to the TEVS board through the computer's USB communications port. See the Quick Start section in the full data sheet for setup and operating instructions.

The EV kit daughter board provides a proven PCB layout to facilitate evaluation of the device and must be interfaced to the appropriate I²C timing signals for proper operation. See Figures 15, 16a, and 16b in the full data sheet for connections and appropriate voltage levels. Refer to the MAX11811 IC data sheet for timing requirements and register addresses.
