Notes
1. All VDD and VSS connections must be made to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 k series resistor.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 mH series inductor.DescriptionThe TDA1306T is a dual CMOS digital-to-analog converter with up-sampling filter and noise shaper. The combination of oversampling up to 4fs, noise shaping and continuous calibration conversion ensures that only simple 1st-order analog post-filtering is required.
The TDA1306T supports the I2S-bus data input mode (fsys = 256fs) with word lengths of up to 20 bits and the LSB fixed serial data input format (fsys = 384fs) with word lengths of 16, 18 or 20 bits. Two cascaded IIR filters increase the sampling rate 4 times.
The DACs are of the continuous calibration type and incorporate a special data coding. This ensures a high signal-to-noise ratio, wide dynamic range and immunity to process variation and component ageing.
Two on-board operational amplifiers convert the digital-to-analog current to an output voltage.
