FUNCTIONAL DESCRIPTION
The TDA1554Q contains four identical amplifiers with differential input stages (two inverting and two non-inverting) and
can be used for single-ended or bridge applications. The gain of each amplifier is fixed at 20 dB (26 dB in BTL). A special
feature of this device is:
Mute/stand-by switch
• low stand-by current (< 100 µA)
• low mute/stand-by switching current (low cost supply switch)
• mute facility
