DA7219-02VBA

DA7219 Audio Codec with Advanced Accessory Detect General Description The DA7219 is an ultra low-power audio codec with Advanced Accessory Detection (AAD), which supports sample rates up to 96 kHz at 24-bit resolution. It contains a mono microphone to analog to digital converter (ADC) path, and a stereo digital to analog converter (DAC) to headphone (HP) path. AAD supports the detection and identification of 3-pole (headphone) and 4-pole (headset) jacks, and allows the automatic pin order switching of MIC/GND on CTIA or OMTP headsets. It also supports automatic multiple button detection.

Revision 3.3 11 of 126 18-Feb-2019 © 2019 Dialog Semiconductor DA7219 Audio Codec with Advanced Accessory Detect 1.1 Terminology Crosstalk (dB) The level difference between the active path output and the idle path measured signal level, at the test signal frequency. The active path is configured and supplied with an input signal capable of driving a full scale output, with the signal measured at the output of the specified idle path. Mute Attenuation The difference in level between the full scale output signal and the output with mute applied. Channel Separation (dB) [left-to-right and right-to-left] The difference in level between the active channel (driven to maximum full scale output) and the signal level measured in the idle channel at the test signal frequency. The active channel is configured and supplied with an input signal capable of driving a full scale output, with the signal measured at the output of the associated idle channel. PSRR The ratio of a given power supply change relative to the output signal that results from it. PSRR is measured under quiescent signal path conditions. SNR The difference in level between the maximum full scale output signal and the output with no input signal applied. THD+N The level of the rms value of the sum of harmonic distortion products plus noise in the specified bandwidth relative to the amplitude of the measured output signal. All performance measurements carried out with 20 kHz low pass filter, and where noted an Aweighted filter. Failure to use such a filter will result in higher THD and lower SNR readings than are found in the Electrical Characteristics. The low-pass filter removes out of band noise; although it is not audible it may affect dynamic specification values. 2 [1] References Android Wired Audio Headset Specification (v1.1) (https://source.android.com/accessories/headset/specification.html ) Datasheet CFR0011-120-00 Revision 3.3 12 of 126 18-Feb-2019 © 2019 Dialog Semiconductor DA7219 Audio Codec with Advanced Accessory Detect 3 Block Diagram DIGITAL ENGINE Impedance Detection Sidetone Path System Controller ADC DACL HP_L DACR HP_R MICBIAS MIC Accessory Detect MIC_N MCLK Input Filters (High-Pass, ALC) MIC_P Tone Generator Output Filters (High-Pass, 5-BandEQ) DA7219 PLL RING2 SLEEVE AAD JACKDET SLEEVE_SENSE RING2_SENSE HPCFP HPCFN HPCSN HPCSP GND_CP VDD GND GND_HP CHARGE PUMP VDD_MIC DATIN DATOUT BCLK VDD_IO SCL SDA WCLK DIGITAL AUDIO INTERFACE I2C CONTROL INTERFACE nIRQ VMID VREF DACREF VOLTAGE REFS Figure 2: DA7219 Block Diagram Datasheet CFR0011-120-00 Revision 3.3 13 of 126 18-Feb-2019 © 2019 Dialog Semiconductor DA7219 Audio Codec with Advanced Accessory Detect 4 Ballout 1 A HPCSP B C 2 3 4 5 HP_L HPCSN D HP_R RING2_ SENSE GND_CP 1 2 8 4 5 DACREF DATIN 6 10 VMID 11 7 9 12 16 MICBIAS MIC_P MIC SCL 11 15 MIC_N RING2 SCL MCLK 10 14 VDD_MIC nIRQ 8 13 GND_HP RING2 GND WCLK 12 SLEEVE DATOUT BCLK VDD_IO VDD_IO 9 VREF VDD 3 7 SLEEVE_ SENSE HPCFN HPCFP 6 SDA 13 14 JACKDET 15 16 View from above “Live Bug” Analogue Digital Power Ground Figure 3: DA7219 Ballout Diagram Table 1: Ball Description Ball No. Ball/Pin Name Type (Table 2) Description Microphone Inputs B16 MIC_P AI Differential analog microphone 1 input (Pos) A15 MIC_N AI Differential analog microphone 1 input (Neg) B14 MICBIAS AO Microphone bias output Accessory Detect D16 JACKDET DI Jack Detect Input from socket A11 SLEEVE AIO Socket Sleeve (configured as MIC or GND) C13 RING2 AIO Socket Ring 2 (configured as GND or MIC) B6 SLEEVE_SENSE AIO Socket Sleeve (Sense) B4 RING2_SENSE AIO Socket Ring 2 (Sense) C15 MIC AIO Microphone DC input Headphone Outputs A3 HP_L AO Single-ended headphone output (Left) A5 HP_R AO Single-ended headphone output (Right) Charge Pump A1 HPCSP AIO Charge pump reservoir capacitor (Positive) C1 HPCSN AIO Charge pump reservoir capacitor (Negative) D2 HPCFP AIO Charge pump flying capacitor (Positive) C3 HPCFN AIO Charge pump flying capacitor (Negative) Digital Interface D14 SDA DIOD I2C bidirectional data D12 SCL DI I2C clock Datasheet CFR0011-120-00 Revision 3.3 14 of 126 18-Feb-2019 © 2019 Dialog Semiconductor DA7219 Audio Codec with Advanced Accessory Detect Ball No. Ball/Pin Name Type (Table 2) Description D10 nIRQ DIOD Interrupt output (open drain active low) C7 DATIN DIO DAI data input to DA7219 C9 DATOUT DIO DAI data output from DA7219 D6 BCLK DIO DAI bit clock D8 WCLK DIO DAI word clock C11 MCLK DI Master clock input References B8 DACREF AIO DAC reference decoupling capacitor A9 VMID AIO Mid-rail reference decoupling capacitor A7 VREF AIO Bandgap reference decoupling capacitor C5 VDD AI Main analog and digital supply A13 VDD_MIC AI Supply for MICBIAS LDO D4 VDD_IO AI Supply for digital interfaces B2 GND_CP AI Ground B10 GND AI Ground B12 GND_HP AI Ground Supplies Grounds Table 2: Ball/Pin Type Definition Ball/Pin Type Description Ball/Pin Type Description DI Digital Input AI Analog Input DIO Digital Input/Output AO Analog Output DIOD Digital Input/Output open Drain AIO Analog Input/Output Datasheet CFR0011-120-00 Revision 3.3 15 of 126 18-Feb-2019 © 2019 Dialog Semiconductor DA7219 Audio Codec with Advanced Accessory Detect 5 5.1 Pin Descriptions Microphone Pins 5.1.1 MIC_P MIC_P is the positive differential input for the analog microphone channel.

It is used to indicate whether the data bits belong to the left or right audio channel. 5.6 5.6.1 Headphone Output Pins HP_L HP_L is the left-channel single-ended headphone output. It is ground-centered so the headphone speaker can be connected directly between HP_L and ground. 5.6.2 HP_R HP_R is the right-channel single-ended headphone output. It is ground-centered so the headphone speaker can be connected directly between HP_R and ground. 5.7 5.7.1 Charge Pump Pins HPCSP HPCSP is the positive output from the headphone charge pump.

The AAD supports the detection of 3-pole (headphone or lineout) or 4-pole (headset) jacks, with automatic pin order switching of MIC/GND on CTIA and OMTP headsets. The DA7219 contains a mono analog microphone-to-ADC path and a DAI for input and output. The DAC to headphone path has a ground-centered, single-ended stereo headphone output. The digital core has an input filter with a high-pass filter (HPF), and automatic level control (ALC), while the output filter has an HPF, and a 5-band equalizer (EQ). There is also a sidetone path with gain and a tone generator that supports Dual Tone MultiFrequency (DTMF). 11.1 Device Operating Modes The DA7219 codec has three operating modes: 11.1.1 DEEP SLEEP There is no clocking in DEEP SLEEP mode and consequently no functionality available and no accessory detection is performed. The system will awake when system_active = 1. 11.1.2 SLEEP In SLEEP mode and with micbias off, AAD performs jack detection and jack configuration detection. Any button press is detected, but identification of the button cannot be performed until micbias is on.
