Product details

Description

ADD_OUT 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 suppl

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 (.
