1 / 113 page  DA7210 Ultra-low power stereo codec Company confidential Datasheet Revision 3a 15-Oct-2015 CFR0011-120-00 Rev 5 1 of 113 © 2015 Dialog Semiconductor 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. Key features ■ Stereo multi-bit Delta Sigma DAC with SNR 100 dB ('A' weighted @ 48 kHz) ■ Stereo multi-bit Delta Sigma ADC with SNR 96 dB ('A' weighted @ 48 kHz) ■ Ultra low-power stereo headphone driver with □ Stereo DAC to HP playback power: 2.5 mW □ 2x58 mW output power (16 Ω) □ ‘Capless’ output via GND centred signals □ Four level charge pump with continuous tracking of audio signal (Class G) □ Short circuit protection ■ Support of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 and 96 kHz sample rates ■ On-chip PLL with signal shaper and audio Sample Rate Matching ■ Wide range of external clocks including industry standard 256xFs, system clock 12, 13, 24, 26 or 27 MHz and low power 32 kHz mode ■ Audio serial data bus supports I2S, left/right justified, DSP and TDM modes ■ Stereo or mono differential microphone interface ■ Programmable ultra-low noise bias supply for electret microphones ■ Volume controlled stereo auxiliary inputs and outputs supporting FM Radio and fixed gain speaker amplifiers ■ Multi-mode audio routing and mixers ■ Pop & click suppression circuitry ■ ASSP DSP filter engine for digital audio enhancements (acoustic filtering, wind noise suppression, 5-band equaliser, 3D sound, automatic gain control) ■ Supports supply from single voltage (1.8/2.5 V) ■ Extensive modular power control ■ Package: 49 bump WL-CSP – 0.4 mm pitch Applications ■ Personal media players ■ Portable consumer devices ■ Music handsets ■ Personal navigation devices |
