DA7212数据手册开发板套件编程器的评估演示板及套件规格书PDF

描述 Description

The DA7212 is a high-performance, low-power audio codec with an enhanced hybrid Automatic Level Control (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 ALC that offers faster reaction times and finer gain resolution to maintain a consistent audio quality level when recording.
