Pop and click performance
The TS4956 has 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 Cin, the output capacitor Cout
(for single-ended configuration) and the bias voltage bypass capacitor Cb.
The values of Cin and Cout are determined by the lower cut-off frequency value requested.
The value of Cb will affect the THD+N and PSRR values in lower frequencies.
The TS4956 is optimized to have low pop and click in the typical schematic configurations
(see
Figure 1 on page 3 and Figure 2 on page 4).

Thermal shutdown
The TS4956 device has internal thermal shutdown protection in the event of extreme
temperatures. Thermal shutdown is active when the device reaches temperature 150°C.
