LA2901V
Overview
The LA2901V 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 LA2901V 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
High output level (5.3Vrms)
Low output noise voltage (12V)
Low total harmonic distortion (0.004%)
High ripple rejection ratio (70dB)
Fewer external parts required
Excellent audio fidelity
