DA7212

Ultra-Low Power Stereo Codec

Datasheet

Revision 3.5

05-Jan-2022

CFR0011-120-00

1 of 135

General Description

The DA7212 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. Comprehensive analogue mixing and bypass paths to the

output drivers are available.

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. The device may be operated in slave or master

modes using the internal PLL which may be bypassed if not required.

To fully optimise each customer application, a range of built in filtering, equalisation and audio

enhancements are available. These are accessible by the processor over the I2C serial interface.
