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.

b. the harmonic distortion at low frequencies can be

decreased by connecting two diodes at pin 15 to ground or

a zener diode of 1.5 V.
