DA7211-01UA6

Codecs Overview

The DA7211-01UA6 is an ultra-low power stereo audio codec featuring a true-ground capless headphone driver. It operates from a single 1.8V supply and supports sample rates up to 96kHz via multi-slot I2S/PCM interfaces. The device integrates a high-efficiency 40mW/channel headphone amplifier with an integrated charge pump. Audio performance includes 100dB DAC SNR and 95dB ADC SNR at 2.5V. It utilizes a 36-bump WLCSP package on a 0.5mm ball pitch, measuring 3mm x 3mm.

Codecs Procurement Notes

Verify the specific suffix UA6 against current Renesas documentation to confirm package type and moisture sensitivity level. Confirm availability status as this variant may be obsolete or have limited stock compared to other revisions. Ensure compatibility with existing PCB layouts designed for the 36-WLCSP form factor before procurement.

Codecs Selection Notes

Select this component for applications requiring high-definition audio in a minimal footprint. The integrated headphone driver eliminates external components, reducing BOM cost. Verify that the system design supports the required 1.8V supply voltage and I2S/PCM interface protocols for proper integration with digital processors.

Codecs Part Context

This part belongs to the DA7211 series of ultra-low power stereo codecs. It shares core functionality with variants like the DA7211-01UA2 but differs in packaging and distribution format. The series is designed for portable digital audio products where power efficiency and audio fidelity are critical constraints.

Codecs Replacement Considerations

The DA7211-01UA2 is a listed alternative within the same family. Verify pinout compatibility and software register settings when substituting. Other family members like the DA7212 offer different power modes but may require design adjustments.
