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
