afterpower-on).
Fig. 25 represents the detailed turn-on transient
with reference to the stereo configuration.
At the power-onthe output decoupling capacitors
are charged through an internal path but the de-
vice itself remains switched off (Phase 1 of the
representeddiagram).
When the outputsreach thevoltage level of about
1V (this means that there is no presence of short
circuits) the device switches on, the SVR capaci-
tor starts charging itself and the output tracks ex-
actly the SVR pin.
During this phase the device is muted until the
SVR reaches the ”P(pán)lay” threshold(~2.5V typ.), af-
ter that the music signal startsbeing played.
Stereo/Bridge Switching
There is also no need for externalcomponents for
changingfrom stereo to bridge configuration(figg.
24-27).
A simple short circuit between two pins allows
phase reversal at one output, yet maintaining the
quiescentoutput voltage.
Stand-by
The device is also equippedwith a stand-byfunc-
tion, so that a low current, and hence low cost
switch, can be used forturn on/off.
Stability
The device is provided with an internal compen-
sation wich allows to reach low values of closed
loop gain.
In this way better performances on S/N ratio and
SVR can be obtained.
