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: Input a 1VP-P, 1kHz sine wave and measure the total-harmonic distortion of the output using a total-harmonic distortion meter. Note 7: Measure the input pin voltage VIN50 when a current of DC50A is flowing into the input pin. Measure the input pin open-circuit voltage. The input impedance is given by Z = (VIN50 - VIN0) / 50 x 10-6[]. 5 Multimedia ICs BA7604N *External dimensions (Units: mm) 25.2 0.2 2.8 0.2 10.5 0.5 5.8 0.2 1.2 1 3.5 0.5 2.54 10 0.6 0.8 1.3 0.3 0.1 SIP10 6 |
