DA7210

Ultra-low power stereo codec

Company confidential

General description

The DA7210 is a high fidelity audio codec with integrated true-ground capless headphone driver

suitable for a variety of low power, digital portable audio products.

Featuring a high efficiency headphone amplifier and supporting economic single supply voltages

down to 1.8 V, the ultra-low 2.5 mW power consumption extends music playback time for battery

operated equipment.

Eight analogue input pins allow multiple audio sources to be internally mixed, eliminating the need for

external switches. Both single-ended and fully-differential line and microphone inputs are supported

with built-in variable gain amplifiers to optimise dynamic range prior to digitisation.

DA7210 provides simultaneous connection to stereo headphone, stereo line outputs, and a mono

differential output. Stereo line outputs can be differential or single-ended. Both stereo outputs have

volume control from -54 dB to +15 dB.

Filtering and gain control is performed digitally including 5-band EQ and a digital input AGC with

programmable attack and decay parameters. A configurable signal processing engine allows various

enhancements and effects on the digital audio signal like acoustic filtering, wind noise suppression

and 3D sound.

The multi-slot I2S/PCM interface supports all common sample rates between 8 and 96 kHz in master

or slave mode operation.
