2 x 1 W portable/mains-fed stereo
power amplifier
The ILA7053N 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.
• No external components
• No switch-ON/OFF clicks
• Good overall stability
• Low power consumption
• Short-circuit-proof

FUNCTIONAL DESCRIPTION
The ILA7053N 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 ILA7053N 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.
