In addition to the overload protection described above, the device features a thermal shutdown circuit
which initially puts the device into a muting state (@ Tj = 145°C) and then into stand-by (@ Tj = 150°C).
Full protection against electrostatic discharges on every pin is included.
5.3 Other Features
The device is provided with both stand-by and mute functions, independently driven by two CMOS logic
compatible input pins.
The circuits dedicated to the switching on and off of the amplifier have been carefully optimized to avoid
any kind of uncontrolled audible transient at the output.
The sequence that we recommend during the ON/OFF transients is shown by Figure 19.
The application of figure 20 shows the possibility of using only one command for both st-by and mute func-
tions. On both the pins, the maximum applicable range corresponds to the operating supply voltage.
