2Vrms analog i/p and o/p line driver from Nuvoton for digital audio apps

Nuvoton Technology has introduced a 2Vrms analog input and output line driver IC- NAU8220. NAU8220 is designed for use in consumer digital audio applications that need 2Vrms stereo outputs, such as set-top boxes, digital LCD/LED TVs, A/V receivers and media DVD / Blu-ray players.

The NAU8220 includes pop/click elimination features and is immune to power supply and other system noise. The NAU8220 features an integrated charge pump enabling true ground referenced inputs/ outputs and full 5.6Vpp output levels, while operating from only a single 3.3V positive supply voltage. The true ground referenced outputs eliminate the output line driving coupling capacitors.

The NAU8220 chip is available in a 14-SOP and 14-TSSOP package. The packaged part is priced below US$0.55 in quantities of 1,000. Samples and both SOP and TSSOP based evaluation boards are available today.
