Mesured with a current meter at test point IA. ICC2 Circuit current2 Measureing conditions are as listed in supplemtary Table. Measured with a current meter at test point IB. Vomax Output dynamic range Decrease V30 gradually, and measure the voltage when the bottom of waveform output is distorted. The voltage is called VCL. Next, increase V30 gradually, and measure the voltage when the top of waveform output is distorted. The voltage is called VOH. Voltage Vomax is calculated by the equation below: Vomax = VOH-VOL Vimax Maximum input Increase the input signal (SG2) amplitude gradually, starting from 700mVP-P. Measure the amplitude of the input signal when the output signal starts becoming distorted. Gv Maximum gain Input SG1, and read the amplitude output at OUT (29, 32, 35). The amplitude is called VOUT (29, 32, 35). Maximum gain GV is calculated by the equation below: ∆Gv Relative maximum gain Relative maximum gain ∆GV is calculated by the equation bellow: ∆GV= VOUT (29)/VOUT (32), VOUT (32)/VOUT (35), VOUT (35)/VOUT (29) VC1 Main contrast control characteristics1 Measureing the amplitude output at OUT (29, 32, 35). The measured value is called VOUT (29, 32, 35). Main contrast control characterics VC1 is calculated by the equation bellow: ∆VC1 Main contrast control relative characteristics1 Relative characteristics ∆VC1 is calculated by the equation bellow: ∆VC1=VOUT (29)/VOUT (32), VOUT (32)/VOUT (35), VOUT (35)/VOUT (29) VC2 Main contrast control characteristics2 Measuring condition and procedure are the same as described in VC1. ∆VC2 Main contrast control relative characteristics2 Measuring condition and procedure are the same as described in ∆VC1. VC3 Main contrast control characteristics3 Measuring condition and procedure are the same as described in VC1. ∆VC3 Main contrast control relative characteristics3 Measuring condition and procedure are the same as described in ∆VC1. 5.0 Waveform output (V) VOH VOL 0.0 GV=20Log (dB) VOUT 0.7 VC1=20Log (dB) VOUT 0.7 |
