STw5098
Dual low power asynchronous stereo audio codec with integrated power amplifiers
Data Brief

Features

Dual 20 bit audio resolution, 8kHz to 96kHz independent rate ADC and DAC Dual I2S/PCM digital interfaces for dual master Sustain complex voice and audio flow with or without mixing Two I2C/SPI compatible independant control interfaces Asynchronous sampling ADC and DAC that 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 Two 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 Four programmable master/slave serial audio data interfaces: I2S, SPI, PCM compatible and other formats Frequency programmable clock outputs Multibit modulators with data weighted averaging ADC and DAC Four DSP functions for bass-treble-volume control, mute, mono/stereo selection, voice channel filters, deemphasis filter and dynamic compression 93 dB dynamic range ADC, 0.001% THD
with full scale with full scale output @ 2.7V 95 dB dynamic range DAC, 0.02% THD performance @ 2.7V over 16 load
