Hi there Hotwaterwizard, i forgot your name :) Thank you very much for your effort, the NTE746 was wrong, but the pic was right, the lowest one ;D But, what is the max VCC for this IC? :( Can i use a 24 Volt tranny with a bridge and a smoothing cap of say 4700 uF or so, or must it have a stabilised 24 Volt VCC? The TV:s i have seen it in have a stabilized 24 Volt VCC(some Luxor TV:s)! I have a bunch of this IC, and want to build an amp for my computer ;D. Maybee it is the same as TDA2030 ???? //Staigen

Hi I need the datasheet for SN76008 IC. Its a sound power output IC in a pentawatt enclosure, probably made by Texas Instruments. TIA

Show us MP, with a schematic! :) //Staigen

Yapp Audioguru, thats the way it was, i belive :)! //Staigen

Hi Alun, if i remember right it is not that simple, some gates was also needed, maybee i'm wrong, please correct me then. //Staigen

Hi Also the diode D1 is connected wrong, it should be connected between +12Volt and the mosfets drain, cathode to +12Volt //Staigen

Hey Glenn, the address was not complete! Wich country do you live in? //Staigen

Hi there The glue is the gap? //Staigen

Hi It communicate both ways, you only need one chip :) You can start by giving me your address(snailmail) :) I found it on a BBS many years ago, before i was out on the internet so much, now its much easier to get information, i belive it was about 10 years ago, or so :) //Staigen

The 16450 i got is good for 115200 bauds. OBSERVE! Its not 16550:s, its 16450:s! They dont have the problems with the buffer, there is no such buffer! //Staigen

The ones i have is 16450, but they are good too, and, i belive, easier to setup. You did not tell me what your baudrate is, is it very fast? Its 40 pin DIP, i think I will look for it later, and send it to you via email, maybee it was here on this site i found them, check //Staigen

Hi 2 wire is serial in one direction only, 3 wire is serial in both directions at the same time. In parallell mode you transfer a whole word at the same time. This is a ADC with a serial I2C bus output How am i going to explain this, the 54/74F164A is only a serial in/parallell out shift register and must have support for framing, start bit, stop bit(s), (parity bit) and so on. An UART have all this built in! I think i have a description of the UART:s used in PC:s somewhere, i can send it over to you, if you want //Staigen

Hi again I'm not sure you need to program them, at least they are easy to program, you just have to set one or a few registers. :) Sure you can, but they need a lot of support IC:s! :( What is your baudrate? The 54/74F164A is very fast(90Mbit/sec)! :) I think i have a few 16450 UART:s, do you want one? //Staigen

Hi there again Glen The first link didn't work :( Eagle is one free software, link right here on the board: http://www.electronics-lab.com/downloads/pcb/index.html There is also others The 16550 is an UART, used in almost all PC:s

Hey Glen, can you describe your project in moore detail, i'm not sure about this feq, i thougt it was a typo for freq(frequency)? //Staigen

Oops! :( I saw this too late: If you want a D/A converter to get the anlog signal back you also need a A/D converter to convert the analog signal to digital data. And if you want to send the data in a serial way you also need PISO(Parallell In Serial Out) converter, here you can use an UART too. Sorry i din't saw this in the beginning :( //Staigen

Hi Glen You need a SIPO(Serial In Parallell Out) converter between the 9 pin connector and the D/A converter. An UART will do this. //Staigen

Hi there Sasa G Check R11 and R12 //Staigen

How do i know that a electrolytic cap is a LOW ESR type when i stand there in the electronics shop, looking at one? The seller says they all are Low ESR, but i'm not sure, he also say the resistors are Low ESR, and he seems not to know what i'm talking about! :( //Staigen

Hi Glenn I'm waiting, and i am curious too! ;D This is very intresting!!!! //Staigen

Hi again To MP: Note that Stephen wanted a simple variable 0-5 Volt output. A simple way to do this is a R2R ladder connected to the parallel output. Also there maybee is needed some sort of latch. //Staigen

Hi there killerleprechaun21, and welcome to this forum :) How accurate must it be? There is a way to accomplish this in an easy way, if it dont have to be very accurate. Just use a R2R ladder connected to your parallel port. If you want moore accuracy you must use a DAC! //Staigen

Ok, let us know when you buy new parts :) //Staigen

Hi there Um...Me123, how is it going with this PSU? //Staigen

Hi Wait a minute, at the same time buy 2 caps, one .22 uF plasic foil and one 10 uF 16V electrolytic! The .22 one is connected between the input terminal and ground and the 10 uF one is connected between output terminal and ground! Than it is ok! ;D //Staigen
