DA7212-01UM2

DA7212-01UM2 is an ultra-low power audio codec targeting portable audio devices. The input paths support stereo FM line input and up to four analogue (or two analogue and two digital) microphones with two independent microphone biases. The headphone output is true-ground class G with integrated charge pump. There is also a differential class AB speaker driver that can serve as a mono lineout. Digital audio transfer to/from the external processor is via a bi-directional digital audio interface that supports all common sample rates and formats. Typical applications are personal media players, audio headphone/headsets, wearables, embedded applications, arduino compatible development systems.
