Product specification
22 W BTL or 2
11 W
stereo power amplifier
TDA1519C
FUNCTIONAL DESCRIPTION
The TDA1519C 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/standby switch which has the following features:
Low standby current (<100
A)
Low mute/standby switching current (allows for low-cost
supply switch)
Mute condition.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
