5 / 13 page Semiconductor Group 35 TDA 5931-65 Characteristics TA = 25 ˚C; VS = 12 V The characteristics data apply to the supply voltage range VS stated or in case of alignment to the alignment instructions (see page 40). All static voltages are referenced to ground if not stated otherwise. The input levels are given as rms values referenced to synchronous peak fPC = 38.9 MHz.
