PCM3008T from Texas Instruments, in a TSSOP-16. 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 | VCOM | passive | ADC/DAC common-voltage decouple pin that must be bypassed to GND with a 0.1 µF ceramic and a 1 µF or larger chemical capacitor placed as close to the pin as possible. |
| 2 | VINR | input | ADC single-ended analog input for the right channel, with 30 kΩ input impedance and 0.6 VCC Vp-p input voltage, AC-coupled through a 0.47 µF to 4.7 µF capacitor. |
| 3 | VINL | input | ADC single-ended analog input for the left channel, with 30 kΩ input impedance and 0.6 VCC Vp-p input voltage, AC-coupled through a 0.47 µF to 4.7 µF capacitor. |
| 4 | GND | power_in | Ground; the analog and digital grounds are internally tied and VCC must be bypassed to this pin. |
| 5 | VCC | power_in | Power supply, 2.1 V min to 3.6 V max (2.4 V typical), bypassed to GND with 0.1 µF ceramic and 10 µF chemical capacitors as close to the pins as possible. |
| 6 | DEM0 | input | De-emphasis control 0 (Schmitt trigger input, 3.3 V tolerant) that selects the DAC de-emphasis mode together with DEM1; the pin must not be left open. |
| 7 | DEM1 | input | De-emphasis control 1 (Schmitt trigger input, 3.3 V tolerant) that selects the DAC de-emphasis mode together with DEM0; the pin must not be left open. |
| 8 | DOUT | output | ADC serial data output in 16-bit left-justified format, forced to zero during ADC power-down and during the initialization sequence. |
| 9 | DIN | input | DAC serial data input in 16-bit right-justified format (Schmitt trigger input, 3.3 V tolerant), which must not be left open because there is no internal pullup or pulldown. |
| 10 | LRCK | input | Sampling clock (left/right channel) input synchronized to SYSCK (Schmitt trigger input, 3.3 V tolerant), which must not be left open because there is no internal pullup or pulldown. |
| 11 | SYSCK | input | System clock input that must be 256fS, 384fS or 512fS, with minimum 15 ns high and low pulse widths and carefully managed duty cycle and jitter (Schmitt trigger input, 3.3 V tolerant). |
| 12 | BCK | input | Bit clock input supporting 64, 48 or 32 BCK clocks per LRCK period (Schmitt trigger input, 3.3 V tolerant), which must not be left open. |
| 13 | PDAD | input | ADC power-down control, active low: low places the ADC in its lowest power mode, and PDAD and PDDA both low put the device into reset. |
| 14 | PDDA | input | DAC power-down control, active low: low places the DAC in its lowest power mode with VOUT forced to VCOM, and PDAD and PDDA both low put the device into reset. |
| 15 | VOUTL | output | DAC single-ended analog output for the left channel, with 0.6 VCC Vp-p output voltage and a 10 kΩ AC-coupled load impedance. |
| 16 | VOUTR | output | DAC single-ended analog output for the right channel, with 0.6 VCC Vp-p output voltage and a 10 kΩ AC-coupled load impedance. |
