●GENERAL DESCRIPTION
●The TDA1305T is a new generation of filter-DAC which features a unique combination of bitstream and continuous calibration techniques. The converter functions as a bitstream converter for low signals while large signals are generated using the dynamic continuous calibration technique, thus resulting in low power consumption, small chip size and easy application.
●FEATURES
●• Easy application
●• 16fs Finite-duration Impulse-Response (FIR) filter incorporated
●• Selectable system clock (fsys) 256fsor 384fs
●• I2S-bus serial input format (at fsys= 256fs) or LSB fixed 16, 18 or 20 bits serial input mode (at fsys= 384fs)
●• Slave-mode clock system
●• Cascaded 4-stage digital filter incorporating 2-stage FIR filter, linear interpolator and sample-and-hold
●• Smoothed transitions before and after muting (soft mute)
●• Digital de-emphasis filter for three sampling rates of 32 kHz, 44.1 kHz and 48 kHz
●• 12 dB attenuation via the attenuation input control
●• Double speed mode
●• 2nd order noise shaper
●• 96 (fsys= 384fs) or 128 (fsys= 256fs) times oversampling in normal speed mode
●• 48 (fsys= 384fs) or 64 (fsys= 256fs) times oversampling in double speed mode
●• Bitstream continuous calibration concept
●• Small outline SO28 package
●• Voltage output 1.5 V (RMS) at line drive level
●• Low total harmonic distortion
●• No zero crossing distortion
●• Inherently monotonic
●• No analog post filtering required
●• Superior signal-to-noise ratio
●• Wide dynamic range (18-bit)
●• Single rail supply (3.4 to 5.5 V).
