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 swiftly drive 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.
