PCM1680DBQR from Texas Instruments, in a SSOP-28-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ZERO1 | output | Zero-flag output 1, set high when the assigned channel data stays at logic 0 for 1024 LRCK periods and active-high by default (ZREV = 0). |
| 2 | MS/ADR | input | Select input for SPI (MS) or address input for I2C (ADR), with a pull-down; the function depends on the MSEL level. |
| 3 | MC/SCL | input | Shift clock input for SPI (MC) or serial clock input for I2C (SCL), with Schmitt-trigger input. |
| 4 | MD/SDA | bidirectional | Serial data input for SPI (MD) or serial data input/output for I2C (SDA); open-drain output in I2C mode and pull-down in SPI mode. |
| 5 | SCK | input | System clock input at 128, 192, 256, 384, 512, 768, or 1152 fS, with Schmitt-trigger input. |
| 6 | DATA1 | input | Serial audio data input for VOUT1 and VOUT2, with Schmitt-trigger input. |
| 7 | BCK | input | Shift clock input for serial audio data, with Schmitt-trigger input. |
| 8 | LRCK | input | Left and right clock input whose frequency equals the sampling rate fS, with Schmitt-trigger input. |
| 9 | VDD | power_in | Digital power supply, 5 V (4.75 V to 5.25 V range). |
| 10 | DGND | power_in | Digital ground. |
| 11 | DATA2 | input | Serial audio data input for VOUT3 and VOUT4, with Schmitt-trigger input. |
| 12 | DATA3 | input | Serial audio data input for VOUT5 and VOUT6, with Schmitt-trigger input. |
| 13 | DATA4 | input | Serial audio data input for VOUT7 and VOUT8, with Schmitt-trigger input. |
| 14 | MSEL | input | I2C/SPI interface select input, with Schmitt-trigger input and pull-down. |
| 15 | VOUT8 | output | Voltage output for the audio signal corresponding to the R-channel on DATA4. |
| 16 | VOUT7 | output | Voltage output for the audio signal corresponding to the L-channel on DATA4. |
| 17 | VCC1 | power_in | Analog power supply, 5 V (4.75 V to 5.25 V range). |
| 18 | AGND1 | power_in | Analog ground. |
| 19 | VOUT6 | output | Voltage output for the audio signal corresponding to the R-channel on DATA3. |
| 20 | VOUT5 | output | Voltage output for the audio signal corresponding to the L-channel on DATA3. |
| 21 | VOUT4 | output | Voltage output for the audio signal corresponding to the R-channel on DATA2. |
| 22 | VOUT3 | output | Voltage output for the audio signal corresponding to the L-channel on DATA2. |
| 23 | VCC2 | power_in | Analog power supply, 5 V (4.75 V to 5.25 V range). |
| 24 | AGND2 | power_in | Analog ground. |
| 25 | VCOM | power_out | Common voltage output that should be bypassed with a 10-µF capacitor to AGND; bipolar zero voltage is 0.486 VCC. |
| 26 | VOUT2 | output | Voltage output for the audio signal corresponding to the R-channel on DATA1. |
| 27 | VOUT1 | output | Voltage output for the audio signal corresponding to the L-channel on DATA1. |
| 28 | ZERO2 | output | Zero-flag output 2, set high under the same zero-detect condition as ZERO1 for its assigned channels. |
