Boost audio quality to hi-fi level STw5201, 24-bit/103 dB SNR stereo audio DAC The STw5201 is a 24-bit, high-quality DAC for portable applications, with an amazing 103 dB signal-to-noise ratio (SNR) for the whole audio path. The power consumption can be scaled down by adjusting the audio quality from 103 to 97 dB SNR (4-steps). The STw5201 is easy to integrate as it can be directly supplied by the battery. Advanced IPs are included to reduce the numbers of external components and the footprint, including the headset driver with no coupling capacitors, as well as a low power PLL generating the DAC clocks from the 32 kHz RTC clock with no need of additional quartz. Main features Audio performances 24-bit stereo DAC, 103 dB SNR (full audio path to amplifier output) -66 dB (0.05%) THD @ 32 Supply Power supply: 2.7 to 4.8 V I/O supply: 1.62 to 3.6 V Power consumption Standby: 5 µW Playback (*): 27 mW (*) includes supply management and headset amplifier General I²S digital interface for audio data I²C interface System clock generation (26, 52, 69 and 104 MHz) True-ground headset driver (no capacitor) 2 x 50 mW over 16 or 32 Stereo single-ended or differential analog input Stereo differential line out www.st.com/audiodac Packages TFBGA-40 TFBGA-40: 4 x 4 x 1.2 mm, 0.5 mm pitch VFQFPN-44 VFQFPN-44: 7 x 7 x 1 mm, 0.5 mm pitch WLCSP-36 WLCSP-36: 2.6 x 2.6 x 0.6 mm, 0.4 mm pitch Key benefits High quality audio (103 dB) Direct connection to the battery Power consumption and dynamic range adjustable (4-steps) Can operate with 32 kHz RTC clock only Few external components and very small footprint (no need for headset coupling capacitors) Click/pop suppression Applications Mobile handsets MP3 players, portable multimedia players and portable navigation devices STw5201 block diagram STw5201 Supply management Line in 24-bit audio DAC Battery 2.7 to 4.8 V Plug detection Ampli Analog audio mixing matrix Stereo Stereo o line ut line out n No capacitor capacitor a Stereo Stereo t headset 32 32 kHz PLL 103 dB stereo audio DAC SRC MCLK I2S I2C -2 V Applications highlight The STw5201 is very easy to implement as all the supply management is embedded in the chip. Very few external components are needed. No decoupling capacitors are required for the headset amplifier. The device can be driven either by the system clock (mode A) or by the 32 kHz RTC clock (mode B). - In mode A, a clock, from 13 MHz, up to 38.4 MHz drives the device. - In mode B, the device is driven by the 32 kHz RTC clock only and is able to generate a system clock (26, 52, 69 or 104 MHz), allowing to switch-off the platform RF PLL, leading to further power saving in playback mode. The sample rate converter manages sampling rates from 8 to 192 kHz. A 4-step register scales down the IC power consumption together with the dynamic range. By adjusting it from 103 to 97 dB, for example, the power consumption is typically reduced by 27%, from 37 to 27 mW. To facilitate the implementation of the device software within a system, the application package also includes a set of physical device drivers (PDD, low-level drivers) as well as logical device drivers (high-level device drivers for OS support) which, when applied, put the device directly into the possible configurations and use cases.
