NAU8220
2Vrms Audio Line Driver
1 General Description
The NAU8220 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 NAU8220 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.
The NAU8220 is specified for operation from -40°C to +85°C, It is packaged in a cost-
effective and space-saving 14-lead SOP and TSSOP packages.
