TECHNICAL DATA
LOW VOLTAGE MONO/STEREO POWER AMPLIFIER
ILA7050
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)
