PCM1725DR

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

PCM1725DR 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 LRCIN input Sample rate clock input for the audio sampling frequency; it is a Schmitt-trigger input and the system clock is synchronized to it.
2 DIN input Audio data input accepting 16-bit data in normal (MSB-first, right-justified) or I2S format; it is a Schmitt-trigger input.
3 BCKIN input Bit clock input for audio data; it is a Schmitt-trigger input.
4 NC unconnected No connection.
5 CAP passive Common pin of the analog output amplifier.
6 VOUTR output Right-channel analog output, centered at VCC/2 with a full-scale output of 0.62 x VCC Vp-p.
7 GND power_in Ground connection for the device.
8 VCC power_in Power supply, specified at 4.5 V to 5.5 V (5 V typical) with absolute maximum of +6.5 V.
9 VOUTL output Left-channel analog output, centered at VCC/2 with a full-scale output of 0.62 x VCC Vp-p.
10 NC unconnected No connection.
11 NC unconnected No connection.
12 DM input De-emphasis control: HIGH turns de-emphasis on and LOW turns it off; de-emphasis operates only at 44.1kHz. It is a Schmitt-trigger input with internal pull-up.
13 FORMAT input Audio data format select: HIGH selects I2S format and LOW selects standard format. It is a Schmitt-trigger input with internal pull-up.
14 SCKI input System clock input, which must be 256fS or 384fS where fS is the audio sampling frequency.
