NCS2211

Low Distortion Audio Power

Amplifier with Differential

Output and Shutdown Mode

Product Description

http://onsemi.com

The NCS2211 is a high performance, low distortion Class A/B

audio amplifier. It is capable of delivering 1ꢀW of output power into an

8ꢀW 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.

D SUFFIX

CASE 751

N2211

It features low distortion performance, 0.2% typical THD + N @

1ꢀW and incorporates a shutdown/enable feature to extend battery life.

The shutdown/enable feature will reduce the quiescent current to 1ꢀmA

maximum.

ALYWG

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

3ꢀXꢀ3 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.
