LA4917H Description
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 ponents 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...
LA4917H Key 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 ponents
- 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)
