MAX11811 Touch Evaluation System (TEVS)

19-5520; Rev 0; 9/10

General Description

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

software running on a PC interfaces to the TEVS board

through the computer’s USB communications port.

See the Quick Start section for setup and operating

instructions.

The EV kit daughter board provides a proven PCB layout

to facilitate evaluation of the device and must be inter-

operation. See Figures 15, 16a, and 16b for connections

and appropriate voltage levels. Refer to the MAX11811

IC data sheet for timing requirements and register

addresses.
