Vomax Output Dynamic Range
Decrease V34 gradually, and measure the voltage when the bottom of waveform output is distorted. The voltage is
called VOL.
Next, increase V34 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

Vimax Maximum Input
Increase the input signal (SG2) amplitude gradually, starting from 700 mV
P-P
. Measure the amplitude of the input
signal when the output signal starts becoming distorted.

Maximum Gain
Input SG1, and read the amplitude output at OUT (33, 38, 41). The amplitude is called VOUT (33, 38, 41).
Maximum gain G
