Monolithic Linear IC
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

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
