Monolithic Linear IC
Audio Output for TV application
5W Monaural Power Amplifier
Overview
LA42031 is 5W monaural AF power amplifier intended for televisions.
Functions
• 3W Monaural (VCC = 9V, RL = 8Ω, THD = 10%).
• 5W Monaural (VCC = 11V, RL = 8Ω, THD = 10%).
• Built-in standby function.
• Built-in mute function.
• Built-in various protection circuit (short to VCC/short to groumd/load shorting/overheating).

Cautions for us
LA42031
1. Short-circuit (power-output short-circuit), ground fault (GND-output short-circuit), and load short-circuit protective
circuits are incorporated. They are activated in case of abnormal connection.
These circuits remain active while such abnormal connection continues and is reset automatically when the
abnormality is removed.
In certain conditions, the protective circuits may be locked and continue to be active even when the abnormality is
removed. In this case, either enter the standby mode or turn OFF the power supply.
2. The thermal protection circuit is incorporated and is activated when the junction temperature (Tj) rises to about 160°C
or more. The output is controlled to return gradually to the attenuated state.
3. When the product is used near the maximum rating, even the slightest change in the condition may cause exceeding of
the maximum rating, resulting possibly in breakdown. Take the sufficient margin for the supply voltage, etc. and
always use the product within a range never exceeding the maximum rating.
