Pulse transformer LL I didn’t found anywhere in our location. Maybe there can be possible to use Published on May View Download 3. Both electrical inputs are galvanic separated from DAC. I choose DAC without oversampling, which has reportedly most devoted sound. Electrical input is connected through pulse transformer with ratio 1: Recommended is pulse transformer LL of Lundahl company.

Power supply for CS use three low-drop stabilisers. Voltages are filtered by tantal capacitors and goes through filter inductors. Near chips are blocked with le33zc capacitors. It’s necessary to cool stabiliser with small piece of aluminium cooler. Every one of parallel connected DACs has his own decoupling capacitor. They are readed in the reset state. Component values are from datasheet and thez are located near circuit casing.

Signal from multiplexor goes to the PLL. Main clock will be synchronized to this signal. Circuit can work with sample frequency 32kHzkHz. It is relatively old circuit which can work without oversampling. He has only 8 pins datasyeet is cheap. On the internet exists many schematics where are connected more pieces of DAC in parallel which improve bit precision of output. I use 10 pieces for vatasheet connection and change values of R15, R16 a R DAC has current outputs and R16 and R17 are simple convertors to voltage output.

Outputs MUST be connected through serial connected capacitors. On the internet I read, that best sound output is with power supply voltage 8V. One piece of TDA has consumption about 50mA with this voltage, that with 10 pieces will be total current consuption about 0. Circuit board is ready for mounting of small cooler. Schematics diagramschematics in Eagle 4 format Component assemblingFirst I drilled all needed holes. Next I solder CS circuit, because I need a much of space around circuit for simple mounting.


I soldered two corner pins and after visual check I soldered next pins. Pins was not datasheeh. You can too go with soldering iron and tin over all pins on one side, but this method is better with smaller parts in TSSOP package. Next I continued with soldering of smaller parts to bigger parts. SMD resistors and capacitors I first fix on the right position with my finger-nail and a little solder on one side. Next I solder second side of part and finally solder first side.

It is my well-established technique, but other people uses other methods. After placing of all SMD parts and one wire connection we can settle classic parts.

Very Low Drop Voltage Regulators With Inhibit

On the end we settle connectors on his place. Parts layoutCircuit boardCircuit board is designed single-sided with one wire junction. SMD components are placed on bottom side and classic components are on the top.

Board has drills for DAC cooler. Size of board matches maximal size of board in a free version of Eagle 4. I find that in Eagle 4. I choosed other one and redrawed wires. Next I rotate one of power connectors for le33zc to use screw terminal. Maybe there can be possible to use transformer from old 10baseT ethernet card or from telco E1 card. Darasheet bought a small ferrit toroid for frequencies MHz.

I wind on them about 15 turns on both input and output. Probably there will be better to have more turns, but it works. Input of CS is much sensitive. Other components datashret commonly available.

I tried to bridge pulse transformer. I tried optical input too, but everything without success. It looks like that on the I2S output is nothing ,e33cz. There should be idle mute sample signal.


It looks like there are some problem with reset of circuit CS I tried to reset him manually many times and I reached only that he somehow works and on output was generated nice loud noise which was muted in a pause.

I tried to place small resistors on signal paths between decoder and DAC some people do this for lower interference but still without success. Finally i replaced circuit CS for another, but situation eatasheet same.

I can not tell where Dxtasheet made mistake. Wiring diagram is relative simple. Circuit is used in another DACs on the internet and there works. UpdateI fixed the problem. I couldn’t find datasheet anywhere on the internet.

After this DAC begins to play very nicely. After two hours there was cracking in a sound.

DACs are really hot and some of them probably dies when they was running without a cooler. Don’t run DACs on 8V voltage without cooler! TS – V1. Audio Broadcasting DAB ; Referenced documents which are not found to be publicly available in the expected location might be found at Documents.
