PCM1771PWR

Texas Instruments · ADCs/DACs - Special Purpose · TSSOP-16

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.
