FED STEREO POWER AMPLIFIER
GENERAL DESCRIPTION
The ILA7053 is an integrated class-B stereo power amplifier in a 16-lead dual-in-line (DIL) plastic package.
The device, consisting of two BTL amplifiers, is primarily developed for portable audio applications but may
also be used in mains-fed applications.

FUNCTIONAL DESCRIPTIO
The ILA7053 is a stereo output amplifier, with an internal gain of 39 dB, which is primarily for use in portable audio
applications but may also be used in mains-fed applications. The current trends in portable audio application design is to
reduce the number of batteries which results in a reduction of output power when using conventional output stages. The
ILA7053 overcomes this problem by using the Bridge-Tied-Load (BTL) principle and is capable of delivering 1.2 W into an
8
load (Vp = 6 V). The load can be short-circuited under all input conditions.
