Philips Semiconductors Product specification
2 x 22 W BTL stereo car radio power
amplifier TDA1552Q
PINNING
FUNCTIONAL DESCRIPTION
The TDA1552Q contains two identical amplifiers with differential input stages and can be used for bridge applications.
The gain of each amplifier is fixed at 26 dB. A special feature of this device is:
Mute/stand-by switch
•low stand-by current (< 100 µA)
•low mute/stand-by switching current (low cost supply switch)
•mute facility.
