NAU8402
1. GENERAL DESCRIPTION
Stereo 24-bit DAC with 2Vrms Line Out
emPowerAudio
The NAU8402 is a high quality 24-bit stereo DAC with 2Vrms analog output capability. This device includes an
integrated charge pump enabling true ground referenced outputs and full 5.6Vpp output levels, while operating from
only a single 3.3V supply voltage. Additionally, the NAU8402 includes automatic 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 NAU8402 is specified for operation from -40°C to +85°C. AEC-Q100 &
TS16949 compliant device is available upon request .
