Product specication
Low voltage mono/stereo power amplier
TDA7050T
GENERAL DESCRIPTION
The TDA7050T is a low voltage audio amplifier for small radios with headphones (such as watch, pen and pocket radios)
in mono (bridge-tied load) or stereo applications.
Features
Limited to battery supply application only (typ. 3 and 4 V)
Operates with supply voltage down to 1,6 V
No external components required
Very low quiescent current
Fixed integrated gain of 26 dB, floating differential input
Flexibility in use mono BTL as well as stereo
Small dimension of encapsulation (see package design example).
