Product Overview
PCM5102APWR is a stereo line-output DAC designed to simplify the analog output stage around an I²S source. DirectPath charge-pump circuitry produces a ground-centered 2.1 VRMS output, eliminating the large series DC-blocking capacitors commonly used with single-supply DAC outputs.
The integrated PLL can generate the internal system clock from BCK, so many systems can use a three-wire audio interface without a separate MCLK. That can reduce processor pins and clock EMI, but BCK/LRCK quality and supported ratios still need to match the datasheet clocking modes.
The exact APWR code is the non-Q1 TSSOP-20 2000-piece reel option rated −25°C to +85°C; it should not be confused with the automotive Q1 order code that uses a different temperature/qualification context.

Functional Highlights
Ground-centered output removes coupling capacitors but not analog-load checks
The line driver can support relatively low line-level loads, yet downstream input impedance, cable capacitance and output filtering still affect settling/distortion.
PLL-based clock simplification can reduce BOM and EMI
Removing MCLK is useful only when the incoming BCK is continuous/stable enough for the selected sample format; clock-loss behavior and mute ramps should be included in system sequencing.
Design Considerations
- Verify the processor’s BCK/LRCK ratio and data format against PCM5102A supported modes.
- Keep charge-pump and analog-output capacitors/routing close to the DAC to avoid injecting switching noise.
- Preserve the non-Q1 APWR temperature/qualification identity in industrial designs that might otherwise assume automotive rating.
