NCS2211_14 Datasheet, PDF (1/11 Pages) ON Semiconductor – Low Distortion Audio Power Amplifier

NCS2211, NCV2211
Low Distortion Audio Power
Amplifier with Differential
Output and Shutdown Mode
Product Description
The NCS2211 is a high performance, low distortion Class A/B
audio amplifier. It is capable of delivering 1 W of output power into an
8 W speaker bridge−tied load (BTL). The NCS2211 will operate over a
wide temperature range, and it is specified for single−supply voltage
operation for portable applications.
It features low distortion performance, 0.2% typical THD + N @
1 W and incorporates a shutdown/enable feature to extend battery life.
The shutdown/enable feature will reduce the quiescent current to 1 mA
maximum.
The NCS2211 is designed to operate over the −40°C to +85°C
temperature range, and is available in an 8−lead SOIC package and a
3 X 3 mm DFN8 package. The SOIC package is pin compatible with
equivalent function and comparable performance to competitive
devices as is the DFN8 package. The DFN8 has a low thermal
resistance of only 70°C/W plus has an exposed metal pad to facilitate
heat conduction to copper PCB material.
Low distortion, high power, low quiescent current, and small
packaging makes the NCS2211 suitable for applications including
notebook and desktop computers, PDA’s, and speaker phones.
