TA1201CNG
TEST CONDITION (V_CC = 9V, Ta = 25±3°C)
BUS MODE
(00) (02) (03) (04) (0B) (0C) (0D) (0F)
MEASUREMENT METHOD
(40) (00) (40) (80) (80) (80) Ad- Ad- (1) Apply the input signal 1 (f₀ = 10kHz, 0.5V_p-p) to pin 39.
just just
(2) Measure the voltage of G and B output signal at picture period at pin 20 and 21
when the data of sub-address (0E, 0F) is set (80) (V_drvcen)
(3) Measure the voltage of G and B output signal at picture period at pin 20 and 21
when the data of sub-address (0E, 0F) is set (FF) (V_drvmax)
G_drvmax = 20ℓog (V_drvmax / V_drvcen)
(4) Measure the voltage of G and B output signal at picture period at pin 20 and 21
when the data of sub-address (0E, 0F) is set (00) (V_drvmin)
G_drvmin = 20ℓog (V_drvmin / V_drvcen)
