HD66325A (TFT Driver)
64-level Grayscale Driver for the TFT
Liquid Crystal Display for XGA Systems
ADE-207-296(Z)
Rev.0.1
April 1999
Description
The HD66325A is a TFT driver LSI suitable for XGA systems (eight HD66325As used). It receives 6-
bit-per-pixel digital display data, and generates and outputs voltages for 64 grayscales. The output
circuit includes an operational amplifier and is capable of alternating outputs of positive-polarity and
negative-polarity voltages on individual output pins. This results in a high-quality display with
minimal crosstalk.
The effective output voltage deviation is limited to about
±
2 mV by incorporating the original
chopper-type amplifier circuit.
