Low voltage mono/stereo power amplifier

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).
