Car stereo two-channel BTL audio frequency power amplifier

15 W (Total output: 25 W + 25 W) LA4705NA P57

20 W (Total output: 30 W + 30 W) LA4708NF P58

•Extremely low levels of impulse noise

•Supports loads as low as RL = 2 Ω

•Superb sound quality design (fL < 10 Hz, fH = 130 kHz)

•Noise filter circuit does not required capacitors

•The turn-on time can be set arbitrarily with an external capacitor

•Built-in standby mode switching circuit (microcontroller support)

•Full complement of protection circuits (Protection against shorting to power, shorting to ground, and load shorting as well as overvoltage and thermal protection circuits)
