ADM8840 Product details

GENERAL DESCRIPTION

The ADM8840 combines a charge pump regulator and a Common Line (COM) driver in a single chip solution for use in TFT LCD’s. The device provides an LCD controller and grayscale DAC supply voltage of 5.0V (±2%), 2 gate drive voltages of +15V and -15V and a COM driver voltage. This COM Driver voltage alternates the polarity of the Common line voltage every line (or every frame) on the display in order to prevent screen-burn occuring over time. The ADM8840 is powered by a single 3.0V supply.



FEATURES

Programmable COM Driver to prevent Screen-Burn

3 Voltages (5.0V,15.0V,-15.0V) from one 3V Supply

Power Efficiency optimised for use with TFT in mobile phones

Low Quiescent Current

Low Shutdown Current (<5uA)

Shutdown Function



APPLICATIONS

Handheld Instruments

TFT LCD Panels

Cellular Phones
