NCP2824FCT2 Evaluation
Board User's Manual
Overview
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 adjusts automatically 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-in the chip.
A simple Single wire interface allows to enable/disable the
non Clipping function and also to configure the maximum
distortion level in the output. A programmable power limit
function is also embedded in order to protect speakers from
damage caused by an excessive sound level.
The intent of the evaluation boards is to illustrate typical
operation of the NCP2824 device for laboratory
characterization. The NCP2824FCT2GEVB schematic is
depicted in Figure 2.
