6 V Power consumption – Stand-by: 1 µW – Playback: 44 mW for 103 dB SNR, 29 mW for 94 dB SNR PTE™ function – Integrated programmable PTE™ memory to store up to 100 ms of music (5120 x 24-bit stereo words).
– Empty PTE™ memory detection pin – Auto-reset interrupt Inputs – I2S digital input up to 50 MHz (in PTE™ mode) – Stereo single ended or differential analog input Clock – 32 kHz only needed in PTE™ mode – System clock input (13 MHz, 19.
2 MHz, 26 MHz and 38.
4 MHz) for standard (continuous) mode – Internal PLL Analog output drivers – Stereo headset amplifier - ‘True ground’ output amplifier (no coupling capacitor).
- 2x50 mW on 32 Ω and 2x80 mW on 16 Ω - 66 dB programmable gain - Plug detection, click/pop suppression, independent right and left channel shutdown control – Stereo differential line out RoHS (lead-free) packages ■ ■ Description The STw5210 is a 24-bit high performance DAC for mobile handset application with 103 dB dynamic range for the whole audio path.
It embeds an innovative PTE™ function that reduces drastically the whole application power consumption.
In this mode, the music is played back autonomously, while the whole system is switched to power saving condition.
The IC is then driven by the 32 kHz clock only.
The device can be used also in a conventional way (continuous mode) and be driven by the system clock.
STw5210 is very easy to integrate...
