Pop and click performance
The TS4956 has an internal pop and click reduction circuitry which eliminates the output
transients, such as, for example, during switch-on or switch-off phases, or during a switch
from one output mode to another, or when changing the volume. The performance of this
circuitry is closely linked to the values of the input capacitor C
(for single-ended configuration) and the bias voltage bypass capacitor C
The values of C
The value of C
The TS4956 is optimized to have low pop and click in the typical schematic configurations
(Figure 1 on page 5
Thermal shutdown
The TS4956 device has an internal thermal shutdown protection in the event of extreme
temperatures. Thermal shutdown is active when the device reaches a temperature of
150° C.
