MAX11835 Evaluation System
Features
The MAX11835 evaluation system (EV system)
demonstrates a complete solution to drive single and
multilayer piezo actuators to create haptic feedback
for products featuring touch interfaces. The MAX11835
efficiently generates any type of user-programmable
waveforms including sine, trapezoidal, square, and
pulse to drive the piezo loads to create custom haptic
sensation. The low-power device directly interfaces
with an application processor/host controller through an
I2C interface and integrates various blocks including a
boost regulator, pattern storage memory, and waveform
generator in one package, thus providing a complete
haptic feedback controller solution.
S Convenient USB Interface
S Touch Panel with Piezo Actuator Mounted for
Haptic Feedback
S Analog Tracking-Mode Capability
S Easy-to-Use WindowsM Graphical User Interface
(GUI) Allows Register Programming for Various
Haptic Waveforms
S All Components Mounted on a Plexiglass Base for
Ease of Handling
S Single-Supply Operation through the USB
S Option for External Power Supply for the Boost
Regulator
The EV system is a multiboard system that includes a
MAXQ2000 USB touch interface board (UTIB) and a
MAX11835 daughter board.
S Separate User’s Guide Available for the Graphical
User Interface
Note: The CD-ROM included with the EV kit contains
a User’s Guide that provides information about the
graphical user interface (GUI).

Note: The MAX11835
���������������������������������������
is not a touch-screen controller and the touch panel is only provided for haptic
feedback purposes, with the 4-wire flex connector left
unconnected.
