MAX17108

MAX17108 19-4347; Rev 0; 10/08 EVAALVUAAILTAIOBNLEKIT 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) liquidcrystal 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 provide 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.
