描述 Description

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).
