Stereo 20W/Ch Class D

Audio Power Amplifier with

Programmable Power Limit

and Selectable Gain

http://onsemi.com

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.

CASE 488AM

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.

MARKING DIAGRAMS

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.
