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
