20V HIGH CURRENT DRIVE

RAIL-TO-RAIL VCOM/GAMMA

BUFFER



DESCRIPTION

The UTC ULV1546 is the quadruple high voltage rail-to-rail

Vcom/Gamma Buffer with low power dissipation. Operating on power

supplies ranging from 5V to 20V, while current consuming is less than

1.2mA / per amplifier. Rail-to-rail output capability and common mode

input ability beyond the rails enable these amplifiers to offer maximum

dynamic range at any supply voltage.

Fast slew rate and settling times, and a high output drive capability

of 300mA peak AC current (sink and source) are also provided by

UTC ULV1546. With so many attractive characteristics， the four

amplifiers inside UTC ULV1546 are ideal for use as voltage reference

buffers in TFT-LCD panel applications for TV, PC, Notebooks, and

mobile computing devices.
