LA4708NF
AF output
•
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)
