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

PROCEDURES
1. Solder all the components according to the schematic, part list and the photo. Notice
the direction of the polarities of the electrolytic capacitors. There is no direction for
the 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 Ohm
for R25 and 0.22uF for C33, 3300pF for C35.
2. To ensure power supply is functional, please do the follow test before plugging in
any ICs and adjust the resistor trimmer (blue) so that the following requirement are
met:
•
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.
For Non-Overclock Sampling (NOS)
1. U6 pin2 (BCK) to U6 pin 16, U6 pin3 (DATA) to U6 pin 15, U6 pin1 (WS) to U6
pin 18.
2. The CS8412 must be put into "master" mode because the standard way its done on
the 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 to
remove the +5V to this pin then attach M0 to GND. Then the CS8412 is in master
mode and will generate word clock and LR clock from the SPDIF. Master mode is
m0=0V m1=+5V m2=0V m3=0V
Thanks Erin for providing the information

TESTING & DEBUGGING
For CS8412/C8414 and SAA7220, check the rms voltages in the following diagram.
1. For TDA1541A, PIN28, PIN27: +5V; PIN26: -5V; PIN15: -15V; PIN5: 0V
2. 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:
