GENERAL DESCRIPTION
The TDA1554Q is an integrated class-B output amplifier in a 17-lead single-in-line (SIL) plastic power package.
The circuit contains 4 x 11 W single-ended or 2 x 22 W bridge amplifiers. The device is primarily developed for car radio
applications.

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