PCM1680DBQR

Texas Instruments · ADCs/DACs - Special Purpose · SSOP-28-150mil

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.
