NCS8353
Stereo 20W/Ch Class D
Audio Power Amplifier with
Programmable Power Limit
and Selectable Gain
The NCS8353 is a stereo Class D audio power amplifier capable of
delivering a continuous power of up to 20 W/ch into an 8
W bridge tied
load (BTL). It can be powered from the existing 24 V rail in Flat Panel
Television (FPTV) systems. The high efficiency of the NCS8353,
86%, reduces the requirement of an external heat sink when driving
high power.
The digital power limit feature can program the output power limit
at 10 W, 12 W, 15 W, or 20 W/ch, allowing the NCS8353 to be a single
system solution in FPTV audio applications.
The NCS8353 includes a digital power limit feature. The digital
power limiter quickly reduces the internal gain of the amplifier when
high amplitude signals would cause excessive clipping on the output.
The NCS8353 minimizes pop and click artifacts in the audio system
by reducing voltage and current transients during power supply
cycling, entering or recovering from shutdown, and mute. The
shutdown feature reduces the quiescent current draw of the amplifier
to 100
mA typical. The mute feature ensures that audio is not present at
the output during audio source switching.
The gain of the NCS8353 is programmed via two gain pins, G0 and
G1, allowing four selectable ranges: 20 dB, 26 dB, 32 dB, and 36 dB.
Auto recovery short circuit and over temperature protection
circuitry are incorporated to ensure device functionality after short
circuit and high temperature events occur.
