Shutdown time
When the standby command is set, the time required to put the two output stages into high
impedance and to put the internal circuitry in shutdown mode, is typically 5ms. This time is
used to decrease the gain and avoid any pop noise during shutdown.
The gain decreases smoothly until the outputs are muted (see
Consumption in shutdown mode
Between the shutdown pin and GND there is an internal 300kΩ resistor. This resistor forces
the TS2007 to be in shutdown when the shutdown input is left floating.
However, this resistor also introduces additional shutdown power consumption if the
shutdown pin voltage is not 0V.
Referring to
example, you must add 0.4V/300k=1.3µA in typical (0.4V/273k=1.46µA in maximum) to the
shutdown current specified in
Single-ended input configuration
It is possible to use the TS2007 in a single-ended input configuration. However, input
coupling capacitors are needed in this configuration. The following schematic diagram
shows a typical single-ended input application.
