Description
STw5098 is a dual low power asynchronous stereo audio CODEC device with headphones amplifiers for high quality audio listening and recording.

Features
■ Dual 20 bit audio resolution, 8kHz to 96kHz independent rate 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

Applications
■ Digital cellular telephones with application processor such as mp3 or gaming and Bluetooth concurrent application
