Global Mixed-mode Technology Inc.

14+1 Channel Voltage Buffers for TFT LCD

Features

General Description

Supply Operation Range : 6.5V to 19.5V

14+1 Channels :

The G1575 consists of 14+1 channel buffers target

toward the needs of thin film transistor liquid crystal

display (TFT LCD). This device incorporates one

Vcom buffer and 14 gamma buffers. Each buffer is

capable of driving heavy capacitive loads and offering

large current loading (Vcom: 100mA, Gammas: 30mA).

--- 14 Gamma Buffers with each Continuous

Output Current of ±30mA (MAX)

--- 1 Vcom Buffer with Continuous Output

Current of ±100mA (MAX)

Supply Current at V_DD=10V : 11mA (TYP)

Unity Gain Vcom Buffer Capable of Driving

Large Capacitive Loads

The G1575 is available in the TQFP7X7-48 and

TQFP7X7-48 (FD) package.

Input Common Mode Range beyond the Rails

Rail-to-Rail Output Voltage Swing
