VP = 5 V; Tamb = 25 °C; nominal input signal Vi1, 2 = 0.25 V RMS value (FM: 54% modulation is equivalent to
∆f = ±27 kHz); nominal input signal Vi1 = 0.5 V RMS value (AM: m = 0.54); nominal input signal
Vi3, 4 = 0.25 V RMS value (AM: m = 0.54); nominal output signal Vo1, 2, 3, 4 = 0.5 V RMS value; fAF = 1 kHz;
Vi pil = 16 mV RMS value; fpil = 54.6875 kHz (identification frequencies: stereo = 117.48 Hz, dual = 274.12 Hz), 50 µs
pre-emphasis; noise measurement in accordance with “CCIR468-3”, operating oscillator frequency fosc = 10.008 MHz;
currents into the IC positive; measured in test circuit Fig.8; unless otherwise specified.
