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.
