- High-performance audio codec with integrated PLL
- True-GND capless Class G 40mW headphone driver with integrated charge pump
- Flexible clocking capability to minimize master clock circuit board routing
- Pop & Click suppression circuitry
- Multi-mode audio routing, mixing and volume control
特性
- Stereo Playback/Record: 2.5mW and 3mW at 1.8V (into stereo headphone load)
- Audio performance at 2.5V
- DAC: 100dB/-85db THD
- ADC: 95db SNR/-86dB THD
- Sample rates up to 96kHz supported via multi-slot I2S/PCM interface
- Stereo fully-differential microphone amplifiers with 5µV input noise and bias
- Package: 36 bump WLCSP on 0.5mm ball pitch
