ILA7050

LOW VOLTAGE MONO/STEREO POWER AMPLIFIER

GENERAL DESCRIPTION

The ILA7050 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)
