Note 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 V
om
(V
P-P
).
Note 2: Input a 1V
P-P
, 1MHz sine wave. The voltage gain is given by G
V
= 20 log (V
OUT
/ V
IN
).
Note 3: Input a 1V
P-P
, 4.43MHz sine wave. The interchannel crosstalk is given by C
T
= 20 log (V
OUT
/ V
IN
).
Note 4: Input 1V
P-P
, 1MHz and 10MHz sine waves. The frequency characteristic is given by G
f
= 20 log (V
OUT
(f = 10MHz) / V
OUT
(f = 1MHz)).
Note 5: Input a 1V
P-P
, 1MHz sine wave. Reduce the CTL pin voltage from V
CC
.
The CTL pin switching level (V
TH
) is the CTL pin voltage at which the Vout level drops below 20mV
P-P
.
Note 6: Measure the input pin voltage V
IN50
when a current of DC50
μ
A is flowing into the input pin. Measure the input pin open-circuit voltage.
The input impedance is given by Z = (V
IN50
- V
IN0
) / 50

].
Note 7: Input a 1V
P-P
, 1kHz sine wave and measure the total-harmonic distortion of the output using a total-harmonic distortion meter.
