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 Vom (VP-P). Note 2: Input a f = 1MHz, VIN = 1VP-P sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN). Note 3: Input a f = 4.43MHz, VIN = 1VP-P sine wave. The interchannel crosstalk is given by CT = 20 log (VOUT / VIN). Note 4: Input f = 1MHz and 10MHz, VIN = 1VP-P sine waves. The frequency characteristic is given by Gf = 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz)). Note 5: Input a f = 1MHz, VIN = 1VP-P 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 f = 1MHz, VIN = 1VP-P sine wave. Increase the CTL pin voltage from 0V. The CTL pin switching level (VTH) is the CTL pin voltage at which the VOUT level goes below 1.0VDC Parameter Symbol Switch settings Measurement method Current dissipation Ammeter Maximum output level Note 1 Voltage gain Note 2 Interchannel crosstalk Note 3 Frequency characteristic CTL pin switching level Note 5 Note 6 Note 4 •External dimensions (Units: mm) SIP10 2.8 ± 0.2 25.2 ± 0.2 0.6 1.3 10 2.54 1 0.3 ± 0.1 0.8 |
