ULV1546

UNISONIC TECHNOLOGIES CO., LTD ULV1546 Preliminary 20V HIGH CURRENT DRIVE RAIL-TO-RAIL VCOM/GAMMA BUFFER CMOS IC  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.  FEATURES * Wide Supply Operation Range +5V~+20V * Beyond the rails input capability * Rail-to-rail output swing * Low supply current, 1.2mA per amplifier (typical) * Wide bandwidth (unit gain) 30MHz-3dB bandwidth * 300mA peak output AC current (typ.) * High slew rate=30V/µs * Unity-gain stable  ORDERING INFORMATION Ordering Number Lead Free Halogen Free ULV1546L-P14-T ULV1546G-P14-T ULV1546L-P14-R ULV1546G-P14-R Package TSSOP-14 TSSOP-14 Packing Tube Tape Reel www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-962.a ULV1546  PIN CONFIGURATION Preliminary VOUTA 1 VINA- 2 VINA+ 3 V...
