NCP2824

Non-Clip and Power Limit

Mono Class D Amplifier

with AGC

Description

The NCP2824 is a Filterless Class D amplifier capable of delivering

up to 2.4 W to a 4 W load with a 5 V supply voltage. With the same

battery voltage, it can deliver 1.2 W to an 8 W load with less than 1%

THD+N. The non−clipping function automatically adjusts the output

voltage in order to control the distortion when an excessive input is

applied to the amplifier. This adjustment is done thanks to an

Automatic Gain Control circuitry (AGC) built into the chip. A simple

Single wire interface allows to the non Clipping function to be enabled

and disabled. It also allows the maximum distortion level in the output

to be configured. A programmable power limit function is also

embedded in order to protect speakers from damage caused by an

excessive sound level.
