LA4919N Description
Monolithic Linear IC LA4919N Overview Two-Channel 10W BTL High-Efficiency TV Audio Output Power Amplifier The LA4919N is a 2-channel 10W BTL high-efficiency power amplifier. By using a signal following switching system for the power supply to the amplifier output stage and by including a nonlinear amplifier in the signal system, the LA4919N holds the number of external ponents to a minimum and reduces the power...
LA4919N Key Features
- High-efficiency 2-channel × 10W BTL power amplifier (VCC = 15V, RL = 8Ω)
- Provided in a DIP-28H package (no heat sink is required)
- The number of required signal-following switching circuits has been held to a single circuit, thus reducing even further
- The output is a fully analog signal, and no switching noise appears on the output lines
- Built-in standby switch (amplifier block/headphone block)
- Built-in headphone amplifier : 2 inputs/2 outputs (VG = 6dB, PO = 60mW)
- Built-in protection circuits (overvoltage and thermal protection circuits)
