CHARACTERISTICS
VP = 8.5 V; Tamb = 25 °C; measured at nominal input signal: ViSK = 8 mV, f = 57 kHz amplitude modulated with
fm = 34.95 Hz and m = 60% for ‘BK-traffic area C’ signal; or with fm = 125 Hz and m = 30% for DK signal.
All pin numbers in this table apply to TDA1579, for TDA1579T refer to Fig.1.
