LA4917H - Monolithic Linear IC Audio Output

Datasheet Summary

Description

This capacitor functions as a ripple filter.

A value of 47µF is recommended.

This capacitor sets the amplifier startup wait time.

Features

  • High-efficiency two-channel 7W BTL power amplifier IC (VCC = 12V, RL = 8Ω).
  • Encapsulated in a DIP-28H package (heat sink free).
  • Requires only one signal-following type switching circuit, contributing to a reduction in the number of external components.
  • Provides analog outputs that generate no switching noise on the output lines.
  • Built-in standby switches.
  • Built-in protection circuits (overvoltage and thermal protection circuits) Specificati.

Ordering number : ENA0322 www.DataSheet4U.com Monolithic Linear IC LA4917H Overview Audio Output for TV application High-Effciency Two-Channel 7W BTL Power Amplifier ICs The LA4917H is a high-effciency two-channel 7W BTL power amplifier IC. Increases in the number of external components are held to a minimum by adopting both a signal-following type switching scheme in the amplifier’s output stage power supply, and a nonlinear amplifier that has nonlinear characteristics in the signal system. The power dissipation (thermal loss) in the actual operating range has been reduced to about 1/2 that of earlier class B amplifier ICs. When used with the DIP-28H package, the IC dispenses with the heat sink and significantly contributes to space saving in the end product case.
