PCM1773PWR 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 | LRCK | bidirectional | Left and right clock that determines which channel is on DATA; its frequency must equal the audio sampling rate, it is an input from an external device in slave mode and is generated as an output in master mode. |
| 2 | DATA | input | Serial audio data input. |
| 3 | BCK | bidirectional | Serial bit clock that clocks the individual bits of DATA; it is an input from an external device in slave mode and is generated as an output in master mode. |
| 4 | PD | input | Reset input; when low, the device is powered down and the mode control registers are reset to default settings. |
| 5 | AGND1 | power_in | Analog ground that is the return for VCC1. |
| 6 | AGND2 | power_in | Analog ground that is the return for VCC2. |
| 7 | VCOM | passive | Decoupling capacitor connection; an external 10-µF capacitor from this terminal to analog ground is required for noise filtering, and the nominal voltage here is 0.5 VCC2. |
| 8 | VOUTR | output | R-channel analog signal output of the lineout amplifiers. |
| 9 | VOUTL | output | L-channel analog signal output of the lineout amplifiers. |
| 10 | AIN | input | Monaural analog signal mixer input that can be mixed with the output of the L- and R-channel DACs; the line input voltage range is 0.584 VCC2 Vp-p. |
| 11 | VCC2 | power_in | Analog power supply for the lineout amplifier circuits; the voltage must be the same as VCC1, with an operating supply range of 1.6 V to 3.6 V. |
| 12 | VCC1 | power_in | Power supply for all analog circuits except the lineout amplifier; the operating supply range is 1.6 V to 3.6 V. |
| 13 | DEMP | input | Hardware control for 44.1-kHz digital de-emphasis, as listed in the PCM1773 hardware-control feature set; the pin's voltage limits are not stated in the provided text. |
| 14 | AMIX | input | Hardware control for monaural analog-in mixing, as listed in the PCM1773 hardware-control feature set; the pin's voltage limits are not stated in the provided text. |
| 15 | FMT | input | Hardware control selecting the audio data format, which for PCM1773 is Left-Justified or I2S; the pin's voltage limits are not stated in the provided text. |
| 16 | SCKI | input | System clock input supporting 128 fS, 192 fS, 256 fS or 384 fS system clock frequencies. |
