FUNCTIONAL DESCRIPTION
The TDA1553Q contains two identical amplifiers with differential input stages and can be used for bridge applications.
The gain of each amplifier is fixed at 26 dB. Special features of this device are:
Mute/stand-by switch
·
low stand-by current (< 100
m
A)
·
low mute/stand-by switching current (low cost supply switch)
·
mute facility.
Loudspeaker protection
1 V, a built-in protection
circuit becomes active and limits the DC voltage across the loudspeaker to
£
1 V. The delay time of the protection circuit
can be controlled by an external capacitor connected to pin 12.
