STw5095
Low Power Asynchronous Stereo Audio Codec with Integrated Power Amplifiers
DATA BRIEF

Features

20 bit audio resolution, 8kHz to 96kHz independent rate ADC and DAC 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 I2C/SPI compatible control I/F. 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 Two 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 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 16 load
