4. Power Management

| Feature | WCD9341 | Cirrus Logic CS47L35 | ESS ES9218P (Sabre) | |---------|---------|----------------------|----------------------| | DAC SNR | 126 dB | 124 dB | 127 dB | | Max PCM | 384 kHz | 192 kHz | 384 kHz | | DSD | Yes (256) | No | No | | Headphone amp | Class-H | Class-G | Class-H with THX AAA | | Integrated DSP | Yes (240 MHz) | Yes (low-power) | No | | Power @ 48 kHz | 22 mW | 18 mW | 28 mW (external LDO) | | Mobile integration | SLIMbus | SoundWire | I²S only |

Verdict: The WCD9341 is superior to Cirrus in SNR and DSD support, but the ESS chip achieves lower THD+N (-112 dB) at the cost of power and no integrated DSP.

For any engineer requesting the WCD9341 datasheet, the electrical specs are the most critical section. Below are typical values based on characterization reports: wcd9341 datasheet
