LA2900M
Two-Channel High-Output Line Amplifier
for Car Audio Systems
Overview
The LA2900M is a 2-channel high-output line amplifier
IC developed for use in car audio systems. It can provide
significant improvements in the signal-to-noise ratio when
used to drive an external power amplifier due to its
significantly increased output voltage as compared to that
of earlier preamplifiers.

The high output of the LA2900M allows it to achieve a
high signal-to-noise ratio and excellent fidelity in audio
systems in which the main unit is connected to an external
amplifier, and can improve the performance of the power
amplifier in such systems.
Functions and Features
• High output level (5.3 V rms)
• Low output noise voltage (12 µV)
• Low total harmonic distortion (0.003%)
• High ripple rejection ratio (70 dB)
• Excellent audio fidelity
