Input
impedance
Note 1: Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the output level until the output distortion is 0.5%.
This output voltage at this time is the maximum output level Vom (VP-P).
Note 2: Input a 1VP-P, 1MHz sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN).
Note 3: Input a 1VP-P, 4.43MHz sine wave. The interchannel crosstalk is given by CT = 20 log (VOUT / VIN).
Note 4: Input 1VP-P, 1MHz and 10MHz sine waves. The frequency characteristic is given by Gf = 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz)).
Note 5: Input a 1VP-P, 1MHz sine wave. Reduce the CTL pin voltage from VCC.
The CTL pin switching level (VTH) is the CTL pin voltage at which the Vout level drops below 20mVP-P.
Note 6: Measure the input pin voltage VIN50 when a current of DC50µA is flowing into the input pin. Measure the input pin open-circuit voltage.
The input impedance is given by Z = (VIN50 - VIN0) / 50 × 10-6 [Ω].
