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
m
A)
·
low mute/stand-by switching current (low cost supply switch)
·
mute facility.
