FUNCTIONAL DESCRIPTION
TDA1553CQ
The TDA1553CQ 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 the device are:
•
standby: low supply current (<100
µA)
•
mute: input signal suppressed
•
operating: normal on condition.
When a short-circuit to ground occurs, which forces a DC
voltage across the loudspeaker of
≥1
V, a built-in
protection circuit becomes active and limits the DC voltage
across the loudspeaker to
≤1
V.
Pin 12 detects the status of the protection circuit (e.g. for
diagnostic purposes).

If any output is short-circuited to ground during the standby
mode, it becomes impossible to switch the circuit to the
mute or operating condition. In this event the supply
current will be limited to a few milliamps.
