Overview

The LA2902V is a high output level 4-channel line

amplifier designed for car audio systems. This line

amplifier provides an output signal with a significantly

higher amplitude than the output signal provided by earlier

preamplifiers. This higher amplitude significantly

improves the signal-to-noise ratio in the connection from

the main unit to the external power amplifier, and results

in improved power amplifier performance.

The LA2902V also significantly reduces the required

mounting area by cutting in half the number of external

capacitors required for boosting the signal-system supply

voltage and is available in SSOP miniature package.

Functions and Features

• High output level (5.3 Vrms)

• Low output noise voltage (17 µV)

• Low total harmonic distortion (0.004%)

• High ripple rejection ratio (65 dB)

• Fewer external parts required

• Excellent audio fidelity
