NAU8401YG TR

ADCs/DACs - Special Purpose Overview

The NAU8401YG TR is a low-power, high-quality stereo audio output system designed for portable applications. It integrates precision 24-bit stereo DACs with integrated drivers for speakers, headphones, and stereo line outputs. The device features on-chip digital signal processing including a 5-band equalizer, 3-D audio enhancement, and automatic level control. It supports standard PCM and I2S interfaces and includes an internal Fractional-N PLL for clock generation. The analog supply operates from 2.5V to 3.6V, while the speaker supply can reach up to 5.5V to drive 1W into an 8Ω load. It is housed in a 32-lead QFN package.

ADCs/DACs - Special Purpose Procurement Notes

Verify that the 'TR' suffix indicates tape-and-reel packaging when sourcing components. Confirm the specific revision (Rev2.6) matches design requirements. Ensure the order quantity aligns with the manufacturer's reel specifications. Check for AEC-Q100 compliance if automotive qualification is required, as this may be available upon request separately.

ADCs/DACs - Special Purpose Selection Notes

Select the NAU8401YG TR for designs requiring a complete audio output solution with minimal external components. It is suitable for battery-powered devices due to its flexible power supply ranges (1.7V digital core, up to 5.5V speaker supply). Use the internal PLL if external crystal oscillators are undesirable. Ensure the application supports the -40°C to +85°C industrial temperature range.
