LA42152
Monolithic Linear IC
Audio Output for TV application
15W × 2ch Power Amplifier
Overview
LA42152 is 15W 2-channel AF power amplifier intended for televisions.
Functions
• 15W × 2 channels (VCC = 16.5V, RL = 8Ω)
• Standby function
• Mute function
• Thermal protection circuit
LA42000 series is power IC which made Pin compatible altogether in 5 to 15W. They consist of four kinds of power ICs
(mono, stereo, mono with volume function, stereo with volume function. They realized PCB layout communalization of an
audio power block of TV).

Usage Note
LA42152
1. Lightening (power supply - output short-circuit), ground fault (GND - output short-circuit), and load short-circuit protection
circuits are incorporated. These protection circuits are activated in case of abnormal connection.
These circuits are active while above abnormal connection continues and reset automatically when such abnormality is
removed.
Depending on operation conditions, the protective circuits remain locked and continue to be active even when abnormal
condition is removed. In this case, turn OFF standby or power supply temporarily and the protective circuits can be reset.
2. The thermal protective circuit is incorporated, which is activated when the junction temperature (Tj) rises to about 160°C or
more, controlling the output gradually to the attenuated condition.
3. During use near the maximum rating, the product may suffer damage if even the slightest fluctuation of condition exceeds the
maximum rating. Be sure to use the product within a range which never exceeds the maximum rating while allowing
sufficient margin for the supply voltage, etc.
