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.
