DESIGNATION DESCRIPTION
6.8 µH, 1.8A,
The AAT1168 have five amplifiers independent. The
operational amplifiers are usually used to drive VCOM
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.
