GENERAL DESCRIPTION
The TDA7053 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.
Features
• No external components
• No switch-ON/OFF clicks
• Good overall stability
• Low power consumption
• Short-circuit-proof.

FUNCTIONAL DESCRIPTION
The TDA7053 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 TDA7053 overcomes this problem by using the Bridge-Tied-Load (BTL) principle and is capable of delivering 1.2 W
into an 8 Ω load (V
P
= 6 V). The load can be short-circuited under all input conditions.
