×: Any of switches 1, 2, or 3 possible.
∗1: Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the input level until the output distortion is 0.5%. This output voltage
at this time is the maximum output level Vom (VP-P).
∗2: Input a 2.0VP-P, 1MHz sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN).
∗3: Measure the input pin voltage VIN50 when a current of DC50µA is flowing into the input pin. Measure the input pin open-circuit voltage VIN0.
The input impedance is given by Z = (VIN50 - VIN0) / 50∗10-6[Ω].
∗4: Input a 1.0VP-P, 1kHz sine wave. Connect a distortion meter to the output and measure the total-harmonic distortion.
