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
