PCM1754DBQR

Texas Instruments · ADCs/DACs - Special Purpose · SSOP-16-150mil

PCM1754DBQR from Texas Instruments, in a SSOP-16-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BCK input Serial audio bit-clock input used to clock serial audio data from DATA pin into the serial shift register on rising edge.
2 DATA input Serial audio data digital input carrying 2's complement MSB-first audio data.
3 LRCK input L-channel and R-channel audio data word clock input used to latch serial audio data into the internal interface registers.
4 DGND power_in Digital ground.
5 NC unconnected No connection.
6 VCC power_in Analog power supply input; 5 V nominal with operating range 4.5 V to 5.5 V.
7 VOUTL output Unbalanced analog output for left channel; 4 VPP typical into 5-kΩ ac-coupled load, biased to 0.5 VCC common-mode voltage.
8 VOUTR output Unbalanced analog output for right channel; 4 VPP typical into 5-kΩ ac-coupled load, biased to 0.5 VCC common-mode voltage.
9 AGND power_in Analog ground.
10 VCOM output Unbuffered common-mode voltage output nominally at 0.5 VCC for decoupling and biasing external circuits.
11 ZEROA output Zero flag output for common L-/R-channel detection; set to logic 1 when both channels data remain at 0 for 1024 sampling periods.
12 TEST input Test configuration input; connect to ground or leave open.
13 DEMP input De-emphasis control input; HIGH enables 44.1 kHz de-emphasis, LOW disables de-emphasis.
14 MUTE input Mute control input; HIGH enables soft mute, LOW disables mute.
15 FMT input Data format select input; LOW for 16- to 24-bit I2S format, HIGH for 16-bit right-justified format.
16 SCK input System clock input for operating digital interpolation filters and multilevel delta-sigma modulators.
