Ultra low power Stereo CODEC with 650µW Always On power mode
Extending the battery life of portable devices
DA7212 is a high performance, low-power audio codec with an enhanced hybrid ALC and a powerful speaker driver targeting wearable, portable and embedded applications. It operates from a single supply and has an internal LDO that can be used to optimize power consumption.
The DA7212 audio codec has exceptionally low always-on power consumption (650µW) which can extend the battery life of portable devices – including wearable devices - in an ‘always-on’ mode enabling constant tracking and instant recognition of voice commands.
It integrates an enhanced hybrid Automatic Level Control (ALC) that offers faster reaction times and finer gain resolution to maintain a consistent audio quality level when recording.
