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 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 BA7602 / BA7602F *External dimensions (Units: mm) BA7602 BA7602F 19.4 0.3 16 9 6.5 0.3 16 6.2 0.3 4.4 0.2 9 10.0 0.2 0.51Min. 1 8 7.62 3.2 0.2 4.25 0.3 1 1.5 0.1 8 0.11 0.3 0.1 1.27 2.54 0.5 0.1 0.4 0.1 0.3Min. 0.15 0 ~ 15 DIP16 SOP16 6 0.15 0.1 |
