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
