INTRODUCTIONINTRODUCTIONINTRODUCTIONINTRODUCTION

TDA1541A DAC is the classic 16 bit DAC developed by Philips, which has beenemployed for high-end audio equipments for over many years. This DAC uses withdigital filter SAA7220 and the digital audio receiver IC CS8412 or CS8414, with 8xoversampling. The output stages are implemented by two stage opamps and large ACcoupling capacitors. There are totally 14 decoupling capacitors around the TDA1541Achip, also large decoupling are used for each supply lines. The digital and analog groundsare well separated before they meet at the terminal ground. Also, this DAC can be re-configured into to non-oversampling mode.




FEATURESFEATURESFEATURESFEATURES

• One TDA1541A/TDA1541, one CS8412/CS8414, and one SAA7220.

• Input: S/PDIF

• Output: stereo single-ended signals (2Vrms)

• Seven independent built-in voltage regulation circuits to power different units.

• Built-in full wave rectification circuits for AC power supply.

• Signal paths are designed with minimum parasitic.

• Dedicated ground and power rails layout design.

• Four large reservoir decoupling capacitors for power rails.

• Power requirements: two 18-20V DC, one 15V AC, and one 9-12V AC.

• PCB dimension: 150mm (W) x 180mm (L)

• PCB thickness: 2.4mm, double layer, 2oz copper.




PROCEDURESPROCEDURESPROCEDURESPROCEDURES

1. Solder all the components according to the schematic, part list and the photo. Noticethe direction of the polarities of the electrolytic capacitors. There is no direction forthe thin film capacitors. Either uses 1K ohm for R25, 0.047uF for C33 for CS8412.Do not assemble C35; R25 = 470ohm and C33 = 68nF for CS8414 Or Use 470 Ohmfor R25 and 0.22uF for C33, 3300pF for C35.

2. To ensure power supply is functional, please do the follow test before plugging inany ICs and adjust the resistor trimmer (blue) so that the following requirement aremet:

• Measure L1, 47uH (5V supply for SAA7220)

• Measure L2, 47uH (-15V supply for TDA1541)

• Measure L3, 47uH (-5V supply for TDA1541)

• Measure L4, 47uH (5V supply for TDA1541)

• Measure L5, 47uH (5V supply for CS8412)

• Measure L6, 47uH (5V supply for CS8412)

• Measure C29, 100nF (+18V supply for AD797/NE5534/OPA627)

• Measure C30, 100nF (-18V supply for AD797/NE5534/OPA627)

3. After checked the power supply, plug in the ICs and turn on the power supply.

4. Enjoy it.

1. U6 pin2 (BCK) to U6 pin 16, U6 pin3 (DATA) to U6 pin 15, U6 pin1 (WS) to U6pin 18.

2. The CS8412 must be put into "master" mode because the standard way its done onthe PCB uses the CS8412 in "slave" mode for the re-clocking. To put into master




mode: remove one leg on the CS8142 adaptor board which is for M0 selector pin toremove the +5V to this pin then attach M0 to GND. Then the CS8412 is in mastermode and will generate word clock and LR clock from the SPDIF. Master mode ism0=0V m1=+5V m2=0V m3=0V

For CS8412/C8414 and SAA7220, check the rms voltages in the following diagram.

1. For TDA1541A, PIN28, PIN27: +5V; PIN26: -5V; PIN15: -15V; PIN5: 0V2. The signal amplitude (RMS) and the clock frequency: PIN1 LE: ~176.4KHz, PIN4

SCK: ~5.63MHz, PIN3 SDATA: 5V digital signal.3. It is normal that the output PIN6 AOR and PIN25 AOL is very weak ~50mV.The

corresponding waveforms are shown as following:
