DA7213 Datasheet Product Factsheet DA7212 stereo CODEC with enhanced automatic level controller and 1.2W speaker driver GENERAL DESCRIPTION KEY FEATURES 100dB stereo audio playback into 16- DA7212 is a high performance, low-power 32 ohm headphones audio codec with an enhanced hybrid ALC and 67mW headphone driver into 16 at a powerful speaker driver targeting portable 2.5V and embedded applications. The audio front- o Minimal external components: end simultaneously supports stereo FM line a capless, true-ground driver input with four analogue (or two analogue and eliminates bulky headphone two digital) microphones with two independent coupling capacitors microphone biases. Comprehensive analogue 1.2W mono speaker driver mixing and bypass paths to the output drivers are available. 3.1mW quiescent power consumption for DAC to headphone playback The headphone output is true-ground Class-G Single supply operation with integrated charge pump. There is also a Stereo digital microphone support differential Class AB speaker driver that can Supports up to four microphones with serve as a mono lineout. two separate low-noise microphone- bias outputs Digital audio transfer to/from the external processor is via a bidirectional I2S interface Low-power PLL provides system that supports all common sample rates. The clocking and audio sample rate device may be operated in slave or master flexibility modes using the internal PLL which may be Built-in 5-band equaliser, ALC and bypassed if not required. noise-gate functions Built-in beep generator that outputs all To fully optimise each customer application, a DTMF keypad values, as well as range of built-in filtering, equalisation and mixing two independently configurable audio enhancements are available. These are sine waves between 10Hz and 12kHz accessible by the processor over the I2C serial 34-ball WLCSP (4.54mm x 1.66mm) interface and can be used to minimise latency package and power consumption.
