AF output

•

Extremely low levels of impulse noise

•

Supports loads as low as RL = 2

•

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)
