The measurements in the above table were made with switching voltage levels for SW1 to SW4 of "L" = 1V, and "H" = 3V.

Note 1: Connect distortion meters to the outputs. Adjust the input level so that the output distortion is 0.5% for a f = 1kHz sine wave input.

This output voltage is the maximum output level Vom (VP-P).

Note 2: Input a f = 1MHz, 1VP-P sine wave. The voltage gain GV = 20 log VOUT / VIN (dB).

Note 3: Input a f = 1MHz and 10MHz, 1VP-P sine wave. The frequency characteristic Gf = 20 log VOUT (f = 10M) / VOUT (f = 1M) (dB).

Note 4: Input a f = 4.43MHz, 1VP-P sine wave.

0dB amplifier SW crosstalk is CTM0, and the 6dB amplifier SW crosstalk is CTM6.

CTM0 = 20 log VOUT / VIN (dB)

CTM6 = 20 log VOUT / VIN + 6 (dB)
