TS4995
Application information
21/26
4.7
Shutdown time
When the standby command is set, the time required to put the two output stages in high
impedance and the internal circuitry in shutdown mode is a few microseconds.
Note:
In shutdown mode, the Bypass pin and Vin+, Vin- pins are shorted to ground by internal
switches. This allows a quick discharge of Cb and Cin.
4.8
Pop performance
Due to its fully differential structure, the pop performance of the TS4995 is close to perfect.
However, due to mismatching between internal resistors Rin, Rfeed, and external input
capacitors Cin, some noise might remain at startup. To eliminate the effect of mismatched
components, the TS4995 includes pop reduction circuitry. With this circuitry, the TS4995 is
close to zero pop for all possible common applications.
In addition, when the TS4995 is in standby mode, due to the high impedance output stage in
this configuration, no pop is heard.
4.9
Single-ended input configuration
It is possible to use the TS4995 in a single-ended input configuration. However, input
coupling capacitors are needed in this configuration. The schematic diagram in Figure 58
shows an example of this configuration.
