10-Channel High-Voltage Scan Driver and VCOM Amplifier for TFT LCD Panels
General Description
The MAX17108 includes a 10-channel high-voltage
level-shifting scan driver and a VCOM amplifier. The
device is optimized for thin-film transistor (TFT) liquid-
crystal display (LCD) applications.
The high-voltage level-shifting scan driver can swing
from +38V to -12V and can swiftlydrive capacitive
loads. There are two positive supply inputs, which pro-
vide flexibility for system design.
The operational amplifier features rail-to-rail output,
high short-circuit output current, fast slew rate, and
wide bandwidth.
The MAX17108 is available in a 28-pin, 5mm x 5mm,
lead-free thin QFN package with a maximum thickness
of 0.8mm for thin LCD panels.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
