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.
