9 / 18 page Data Sheet S13607EJ3V0DS 7 µµµµPD16647 4.1 γγγγ-Corrected Power Circuit The reference power supply of the D/A converter consists of a ladder circuit with a total of 64 resistors, and resistance Σri between γ -corrected power pins differs depending on each pair of γ -corrected power pins. One pair of γ -corrected power pins consists of seven or eight series resistors, and resistance Σri in the figure below is indicated as the sum of the seven or eight resistors. The resistance ratio between the γ -corrected power pins (Σri ratio) is designed to be a value relatively close to the ratio of the γ -corrected voltages V1 through V8 (gray scale voltages in 7 steps) used in an actual LCD panel. Under ideal conditions where there is no difference between the two, therefore, there is no voltage difference between the voltage of the γ -corrected power supplies and the gray scale voltages in 7 steps of the resistor ladder circuits of the µ PD16647, and no current flows into the γ -corrected power pins V1 through V8. As a result, a voltage follower circuit is not necessary.
