Monolithic Linear IC
LA4224
Overview
Audio Output for TV application
1W Monaural Power Amplifier
LA4224 is a 1W monaural power amplifier intended for television audio output.
This IC requires only two external components (capacitors) to construct amplifiers and is ideal for realizing substantial
cost reduction of electronic devices.
Functions
•
1W monaural power amplifier (VCC = 9V, RL = 8Ω).
•
Built-in Mute transistor.

Application Circuit Example
Specifications of any and all SANYO Semiconductor 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 Semiconductor 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.
