LA42051 - 5W X 1ch Power Ampilfier

General Description

C1 : Input coupling capacitor, for which 1.0μF is recommended.

The potential of input pin is 2VBE (about 1.4V).

Therefore, the polarity must be determined according to the DC potential of the circuit connected to the previous step of LA42051.

Key Features

  • PO1 5W×1ch (VCC = 18V, RL = 8Ω).
  • Built-in standby function.
  • Pop noise reduction function.
  • Ripple filter.
  • 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). Model name LA42051 LA42052 LA42351 LA42352 LA42071 LA42072 LA.
