FUNCTIONAL DESCRIPTION

The TDA1552Q 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. A special feature of this device is:

Mute/stand-by switch

low stand-by current (< 100

µ

A)

low mute/stand-by switching current (low cost supply switch)

mute facility.
