RENESAS DA7210-00UC6

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.
