Philips Semiconductors Product specification
22 W BTL or 2 x 11 W stereo car radio
power amplifier
TDA1519A
PINNING
FUNCTIONAL DESCRIPTION
The TDA1519A contains two identical amplifiers with differential input stages. The gain of each amplifier is fixed at 40 dB.
A special feature of this device is the mute/stand-by switch which has the following features:
• Low stand-by current (< 100 µA)
• Low mute/stand-by switching current (low cost supply switch)
• Mute condition.
