• Manufacturer Part Number: AAT1168-Q5-T
• Description: TRIPLE-CHANNEL TFT LCD POWER SOLUTION WITH OPERATIONAL AMPLIFIERS
• Manufacturer: AAT [Advanced Analog Technology, Inc.]

Operational Amplifier
The AAT1168 have five amplifiers independent. The
operational amplifiers are usually used to drive V
and the gamma correction divider string for TFT-LCD.
The output resistors and capacitors of amplifiers are as
low pass filter and compensator for unity GAIN stable.
