PCM1801U

Texas Instruments · ADCs/DACs - Special Purpose · SOIC-14

PCM1801U from Texas Instruments, in a SOIC-14. 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	VINL	input	Left-channel analog input with a full-scale input of 2.828 Vp-p, a 2.1 V center voltage and 30 kΩ input impedance.
2	VINR	input	Right-channel analog input with a full-scale input of 2.828 Vp-p, a 2.1 V center voltage and 30 kΩ input impedance.
3	DGND	power_in	Digital ground, not internally connected to AGND, and should be connected directly to AGND under the package with low impedance.
4	VDD	power_in	Digital power supply, 4.5 V to 5.5 V (5 V nominal).
5	SCKI	input	System clock input (Schmitt-trigger, TTL family) that must be 256 fS, 384 fS, or 512 fS, with an 8.192 MHz to 24.576 MHz range.
6	BCK	input	Bit clock input (Schmitt-trigger) for the audio data interface, with a minimum BCK period of 300 ns.
7	LRCK	input	Sampling clock (word clock) input (Schmitt-trigger), which must be synchronized to SCKI, over a 4 kHz to 48 kHz sampling range.
8	DOUT	output	Audio data output, forced to zero during power-on reset, with a recommended load capacitance of 10 pF maximum.
9	BYPAS	input	HPF bypass control with a 100-kΩ typical internal pulldown; LOW enables the high-pass (dc cut) filter and HIGH bypasses it.
10	FMT	input	Audio data format select with a 100-kΩ typical internal pulldown; LOW selects 16-bit left-justified and HIGH selects 16-bit I2S.
11	VCC	power_in	Analog power supply, 4.5 V to 5.5 V (5 V nominal).
12	AGND	power_in	Analog ground, not internally connected to DGND.
13	VREF2	passive	Reference 2 decoupling pin; a 4.7 µF tantalum capacitor is recommended from VREF2 to AGND, placed as close as possible to the pin.
14	VREF1	passive	Reference 1 decoupling pin; a 4.7 µF tantalum capacitor is recommended from VREF1 to AGND, placed as close as possible to the pin.
