To conveniently serve both needs, its minimum recommended value is 22µF, 47µF can be used to optimize pop performances. 3.2 ) s ( ct u d o Input stage r P e The TDA7389’s inputs are ground-compatible and can stand very high input signals (± 8Vpk) without any performances degradation. t e l o If the standard value for the input capacitors (0.1µF) is adopted, the low frequency cut-off will amount to 16 Hz. s b O The input capacitors should be 1/4 of the capacitor connected to AC-GND pin for optimum pop performances. ) (s 3.3 Standby and muting t c u Standby and Muting facilities are both 3.3V CMOS-compatible. If unused, a straight connection to Vs of their respective pins would be admissible. d o r Conventional/low-power transistors can be employed to drive muting and stand-by pins in absence of true CMOS ports or microprocessors. R-C cells have always to be used in order to smooth down the transitions for preventing any audible transient noises. P e s b O t e l o Since a DC current of about 10µA normally flows out of pin 23, the maximum allowable muting-series resistance (R2) is 70 k, which is sufficiently high to permit a muting capacitor reasonably small (about 1µF). If R2 is higher than recommended, the involved risk will be that the voltage at pin 23 may rise to above the 1.2V threshold voltage and the device will consequently fail to turn OFF when the mute line is brought down. About the standby, the time constant to be assigned in order to obtain a virtually pop-free transition has to be slower than 2.5V/ms. 11/14 Package information 4 TDA7389 Package information In order to meet environmental requirements, ST (also) offers these devices in ECOPACK® packages.
