Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CCLK | input | I2C serial clock input for register configuration; the chip address is 0011 00x where x equals CE, and the bus runs at up to 400 kbps. |
| 2 | MCLK | input | Master clock input supporting standard audio clocks, USB 12/24 MHz clocks and other non-standard clocks, with MCLK frequency up to 51.2 MHz. |
| 3 | PVDD | power_in | Power supply for the digital input and output pins, with a recommended operating range of 1.6 V to 3.6 V (3.3 V typical). |
| 4 | DVDD | power_in | Digital core power supply, with a recommended operating range of 1.6 V to 3.6 V (3.3 V typical). |
| 5 | DGND | power_in | Digital ground connection. |
| 6 | SCLK/DMIC_SCL | bidirectional | Serial audio bit clock (I/O) for the I2S/PCM port, which doubles as the DMIC bit clock; SCLK frequency is specified up to 26 MHz. |
| 7 | ASDOUT | output | ADC serial audio data output, with data driven on the falling edge of SCLK. |
| 8 | LRCK | bidirectional | Left/right channel frame clock (I/O) for the serial audio port, with LRCK frequency specified up to 200 kHz. |
| 9 | DSDIN | input | DAC serial audio data input, sampled by the device on the rising edge of SCLK. |
| 10 | AGND | power_in | Analog ground connection. |
| 11 | AVDD | power_in | Analog power supply, with a recommended operating range of 1.7 V to 3.6 V (3.3 V typical). |
| 12 | OUTP | output | Positive side of the differential analog output, with full-scale output level of AVDD/3.3 Vrms. |
| 13 | OUTN | output | Negative side of the differential analog output, with full-scale output level of AVDD/3.3 Vrms. |
| 14 | DACVREF | passive | Filtering capacitor connection for the DAC reference; the datasheet recommends locating decoupling capacitors as close to the package as possible. |
| 15 | ADCVREF | passive | Filtering capacitor connection for the ADC reference; the datasheet recommends locating decoupling capacitors as close to the package as possible. |
| 16 | VMID | passive | Filtering capacitor connection for the mid-rail (VMID) reference. |
| 17 | MIC1N | input | Negative side of the single microphone analog input pair, with 6 kΩ input impedance and full-scale input level of AVDD/3.3 Vrms. |
| 18 | MIC1P/DMIC_SDA | input | Positive side of the microphone analog input pair; also serves as DMIC data (SDA) when digital microphone mode is used. |
| 19 | CDATA | bidirectional | I2C serial data line (I/O) for register read and write access, sampled while CCLK is high. |
| 20 | CE | input | I2C chip address select; its level sets the x bit of the chip address 0011 00x. |
| 21 | PGND | power_in | Ground connection shown as pin 21 (PGND) in the typical application circuit; it is not listed in the pin table. |
