ULV1546

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.
