LA42072
Overview
LA42072 is 7W 2-channel AF power amplifier intended for televisions.
Functions
7W × 2 channel (VCC = 12V, RL = 8).
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).
