Features:
Market-leading low out-of-band noise
Selectable digital filter delay and performance
No capacitors required to block DC current
Integrated negative charge pump
Internal no-pop control for sample rate changes or clock stop
Intelligent squelch system: soft rising or falling ramp and analog squelch for 120dB squelch signal-to-noise ratio (SNR) with no-pop operation
Integrated high-performance audio phase-locked loop (PLL) with BCK reference to internally generated SCK

Parameter:
Model: PCM5102
Type:I2S Digital to Analog Converter Decoder
Since it's digital audio, it sounds really good, much better than the onboard analog audio. The stereo jack comes soldered onto the board already.
Line out stereo jack
PHAT format board
Uses the PCM5102A Digital to Analog Converter to work with the Raspberry Pi I2S interface
Size: 32x17mm

Dynamic Range: 112dB
SNR:112dB
THD:-93dB
Full-scale output: 2.1VRMS (centered on GND)
Normal 8x oversampling digital filter delay: 20/fS
Low latency 8x oversampling digital filter delay: 3.5/fS
Sampling frequency: 8kHz to 384kHz
System clock multiplier (fSCK): 64, 128, 192, 256, 384, 512,768,1024,1152,1536,2048, 3072; up to 50MHz.
Accepts 16, 24, and 32-bit audio data
PCM data format: I2S, left justified
When LRCK and BCK Automatically enters power saving mode when deasserted
3.3V fail-safe low voltage CMOS (LVCMOS) digital input
Hardware configuration
Single supply operation:- 3.3V analog, 3.3V digital
Integrated power-on reset

How to solve the noise problem:
optional digital filter delay and performance, No need to isolate the DC current capacitor.If there is noise when GND and SCK are connected, this problem can be solved.
