PCM1771PWR 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 | input | Left and right clock input that determines which channel is being input on the audio data input DATA; LRCK frequency must be the same as the audio sampling frequency (5 to 50 kHz). |
| 2 | DATA | input | Serial audio data input that accepts 16- to 24-bit audio data, clocked in on rising edge of BCK. |
| 3 | BCK | input | Serial bit clock input that clocks the individual bits of the audio data input DATA. |
| 4 | PD | input | Reset input that when held low powers down the PCM1771 device and resets all mode control registers to default settings. |
| 5 | AGND | power_in | Analog ground that is a return for VCC. |
| 6 | HGND | power_in | Analog ground that is a return for VHP. |
| 7 | VCOM | output | Decoupling capacitor connection with external 10-µF capacitor required from this terminal to analog ground for noise filtering; voltage level is nominally 0.5 VHP. |
| 8 | HOUTR | output | R-channel analog signal output of the headphone amplifier with full-scale output voltage of 0.55 VHP peak-to-peak and output power of 13 mW stereo at RL = 16 Ω. |
| 9 | HOUTL | output | L-channel analog signal output of the headphone amplifier with full-scale output voltage of 0.55 VHP peak-to-peak and output power of 13 mW stereo at RL = 16 Ω. |
| 10 | AIN | input | Monaural analog signal mixer input that can be mixed with the outputs of the L- and R-channel DACs with analog input voltage range of 0.584 VHP peak-to-peak. |
| 11 | VHP | power_in | Analog power supply for the headphone amplifier circuits with voltage level that must be the same as VCC in range of 1.6 to 3.6 V. |
| 12 | VCC | power_in | Power supply for all analog circuits except the headphone amplifier with recommended voltage range of 1.6 to 3.6 V. |
| 13 | DEMP | input | De-emphasis control input; when high enables 44.1-kHz de-emphasis filter. |
| 14 | AMIX | input | Analog mixing control input; when high enables mixing of external signal AIN with headphone outputs HOUTL and HOUTR. |
| 15 | FMT | input | Data format select input; low selects 16- to 24-bit left-justified format and high selects 16- to 24-bit I2S format. |
| 16 | SCKI | input | System clock input requiring clock frequencies of 0.64 to 19.2 MHz for operating the digital interpolation filters and multilevel ∆-Σ modulators; SCKI can be 128fS, 192fS, 256fS, or 384fS relative to sampling frequency. |
