Description :

Ordering number : ENA0316 Monolithic Linear IC LA42152 Overview Audio Output for TV application 15W × 2ch Power Amplifier 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).

The input circuit is of a zero bias type, so that the input pin potential is close to zero volts. Therefore, the polarity must be determined depending on the DC potential of a circuit connected in the previous stage of LA42152. : Capacitor for the starting time of ripple filter and amplifier, which is recommended to be 47µF. : Capacitor and resistor for muting. C4 is necessary even when no muting function is provided. : Power supply capacitor. : Capacitors an […]
