Shutdown time
When the standby command is activated (both channels put into standby mode), the time
required to put the two output stages of each channel in high impedance and the internal
circuitry in shutdown mode is a few microseconds.
In shutdown mode when both channels are in standby, the Bypass pin and L

Pop performance
Due to its fully differential structure, the pop performance of the TS4997 is close to perfect.
However, due to mismatching between internal resistors R
external input capacitors C
mismatched components, the TS4997 includes pop reduction circuitry. With this circuitry,
the TS4997 is close to zero pop for all possible common applications.
In addition, when the TS4997 is in standby mode, due to the high impedance output stage in
this configuration, no pop is heard.
Single-ended input configuration
It is possible to use the TS4997 in a single-ended input configuration. However, input
coupling capacitors are needed in this configuration. The schematic diagram in
shows an example of this configuration for a gain of +6dB set by the input resistors.
