MAX11850/MAX11851 Evaluation Systems
General Description
The MAX11850/MAX11851 evaluation systems (EV sys-
tems) demonstrate the low-power projected capacitance
touch-sensor controller, which targets power-sensitive
applications such as handheld devices. The EV systems
include built-in control firmware and a Windows
M
graphi-
cal user interface (GUI) to exercise some of the features
of the MAX11850/MAX11851.
Each EV system is a multiboard system offered with or
without haptics and consists of a MAXQ2000 USB touch
interface board (UTIB2), a MAX11850 or MAX11851
daughter board, and a MAX11835 daughter board
(haptic versions only).
