NAU8220SG

DS_NAU8220SG_BlockDiagram

 

The NAU8220SG is a high quality 2Vrms analog input and output line driver. This device includes an integrated charge pump enabling true ground referenced inputs and outputs and full 5.6Vpp output levels, while operating from only a single 3.3V positive supply voltage.

Additionally, the NAU8220SG includes pop/click elimination features and high immunity to power supply and other system noise. This enables fast and efficient system integration while minimizing external component costs.

Target Applications:

Portable Audio Device
