TEST NOTES
1. The output impedance is approximately 32Ω. Therefore, to ensure output matching, connect an external resistor
of 43Ω.
2. 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 multiplied by 2 is the maximum output level Vom (VP-P).
3. Input a 1VP-P, 1MHz sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN) + 6.
4. Input a 1VP-P, 4.43MHz sine wave. The interchannel crosstalk is given by CT = 20 log (VOUT / VIN).
5. Input 1VP-P, 1MHz and 10MHz sine waves.
The frequency characteristic is given by GF= 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz)).
6. 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.
