Adjust the input level until the output distortion is 0.5%. 2: Input a 1VP-P, 1MHz sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN). 3: Input a 1VP-P, 4.43MHz sine wave. The interchannel crosstalk is given by CT = 20 log (VOUT / VIN). 4: Input 1VP-P, 1MHz and 10MHz sine waves. The frequency characteristic is given by Gf = 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz)). 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. This output voltage at this time is the maximum output level Vom (VP-P). *External dimensions (Units: mm) BA7611AN BA7611AF 19.3 0.2 10.5 0.5 5.8 0.2 2.8 0.2 5.0 0.2 8 5 1.2 6.2 0.3 1 3.5 0.5 2.54 8 0.6 0.8 1.3 0.3 0.1 4.4 0.2 1.5 0.1 1 4 0.11 1.27 0.4 0.1 0.3Min. 0.15 SIP8 SOP8 4 0.15 0.1 |
