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.
