Product specication
TV and VTR stereo/dual sound processor
with digital identication and I2C-bus control
TDA9840
CHARACTERISTICS
VP =5V; 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 Vi3,4 = 0.5 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 (identication frequencies: stereo = 117.48 Hz,
dual = 274.12 Hz), 50
s pre-emphasis; noise measurement in accordance with “CCIR468-3”, working oscillator
frequency fω = 10.008 MHz; currents into the IC positive; measured in test circuit according to Fig.5; unless otherwise
specied.
