STW5098
Overview
STw5098 is a dual low power asynchronous stereo audio CODEC device with headphones amplifiers for high quality audio listening and recording. Two I2S/PCM digital interfaces are available, one per master for example Bluetooth and Application Processor, enabling concurrent audio and voice flow between Network and user.
- Dual 20 bit audio independent rate * * *
- resolution, 8kHz to 96kHz ADC and DAC Dual I2S or PCM digital interfaces for dual master Sustain complex voice and audio flow with or without mixing I2C/SPI compatible control I/F Asynchronous sampling ADC and DAC: they do not require oversampled clock and information on the audio data sampling frequency (fs). Jitter tolerant fs Wide master clock range: from 4MHz to 32MHz Stereo headphones drivers, handsfree loudspeaker driver, line out drivers Mixable analog line inputs Voice filters: 8/16kHz with voice channel filters Automatic gain control for microphone and linein inputs Frequency programmable clock outputs Multibit Σ∆ modulators with data weighted averaging ADC and DAC DSP functions for bass-treble-volume control, mute, mono/stereo selection, voice channel filters, de-emphasis filter and dynamic compression 93 dB dynamic range ADC, 0.001% THD with full scale output @ 2.7V 95 dB dynamic range DAC, 0.02% THD performance @ 2.7V over 16Ω load STw5098 LFBGA 6x6x1.4 (112 pins) VFBGA 5x5x1 (112 pins) * * * * * * *
