Monolithic Linear IC
LA9410
Final Audio Output IC for LD Players
Overview
The LA9410 final audio output IC for laser disk players
has an internal input amplifier for the 1-bit DAC, 40 kHz
LPF, digital/analog signal select circuit, output mute,
volume circuit, mixing amplifier and limitter circuit for
RF output, and voltage regulator for plus and minus
power supply, It provides a compact implementation of
audio output circuitry for LD and CD compatible players
and laser karaoke systems.
Functions
• Input amplifier for 1-bit DAC, LPF
• Input signal select (digital/analog audio)
• Output mute
• Volume circuit (for headphone amplifier. No
headphone drive output amplifier is provided)
• Mixing amplifier for RF output (with internal limitter
circuit)
• Regulated power supply circuit (internal use only.
Cannot be output to external circuits)
Features
• Provides compact implementation of LD player output
circuits
• Suitable for 1-bit DAC
• Internal voltage regulator allows direct use of non-
regulated power supply
• Package: DIP-28S

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

3. Power supply
In the LA9410 the IC is protected from high voltage inputs by series resistors located in the power supply, and
voltage regulator circuits in the IC. This means that IC current dissipation will be strongly affected by supply
voltage and the series resistance. Power supply design requires sufficient leeway so that the allowable power
dissipation of the IC is not exceeded.
Note: Use a series resistance in the power supply so that the IC current dissipation is 38mA or less.
4. Measurement of separation and crosstalk
The effects of the IC evaluation circuit board pattern may make accurate measurement of crosstalk and
separation impossible. This is especially common when the peripheral resistor of the 1-bit DAC input circuit
has a high resistance.
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.
In the event that any or all SANYO products (including technical data, services) described or contained
herein are controlled under any of applicable local export control laws and regulations, such products must
not be exported without obtaining the export license from the authorities concerned in accordance with the
above law.
