GENERAL DESCRIPTION
The TDA1558Q is a monolithic integrated class-B output
amplifier in a 17-lead single-in-line (SIL) plastic power
package. The device contains 4 x 11 W single-ended or
2 x 22 W BTL amplifiers and has been primarily developed
for car radio applications.

FUNCTIONAL DESCRIPTION
The TDA1558Q contains four identical amplifiers with
differential input stages (two inverting and two
non-inverting), and can be used for single-ended or BTL
applications. The gain of each amplifier is fixed at 40 dB
(46 dB in BTL). Special features of this device are:
a. mute/stand-by switch
low stand-by current (< 100 µA)
low mute/stand-by switching current (low cost supply
switch)
mute facility.
