Wake-up time (t
When the standby is released to set the device ON, there is a delay of 1ms typically. The
TS2012 has an internal digital delay that mutes the outputs and releases them after this
time in order to avoid any pop noise.
The gain increases smoothly (see
and G0 pin
Shutdown time
When the standby command is set, the time required to set the output stage considered into
high impedance and to put the internal circuitry in shutdown mode, is typically 1ms. 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 (+-/20%) resistor. This
resistor forces the TS2012 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.
With a 0.4V shutdown voltage pin for example, you must add 0.4V/300kΩ=1.3µA in typical
(0.4V/240kΩ=1.66µA in maximum for each shutdown pin) to the standby current specified in

Single-ended input configuration
It is possible to use the TS2012 in a single-ended input configuration. However, input
coupling capacitors are mandatory in this configuration. The schematic diagram in
shows a typical single-ended input application.
