Product specification
4 x 11 W single-ended or 2 x 22 W power
amplifier with distortion detector
TDA1555Q
PINNING
FUNCTIONAL DESCRIPTION
The TDA1555Q 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). Special
features of this device are:
Mute/stand-by switch
• low stand-by current (< 100 µA)
• low mute/stand-by switching current (low cost supply switch)
• mute facility
Distortion detector
• At onset of clipping of one or more channels the distortion detector (pin 15) becomes active. This information can be
used to drive a sound processor or DC volume control to decrease the input signal and so limit distortion.
