Witch IC's?

[Guest den_Juin]

On Ti.com i can choose diffrent kinds of IC-samples, witch should i use?

for 74HC165 i can choose from:

You always need to use the N package as it will fir the sockets.

I have the SN74HC595N, I guess it's the good one over the CD version... Anyone can confirm ?

Witch ICs were eliminated during the inquisition

Hi

go for the: CD74HC165E and the SN74HC595N

you can also get the 4051: CD4051BE

And the RS-232 line driver fot the LTC modual: MAX232IN

another IC worth checking out in the :INA103KP (Very high quality instrumentation op-amp manufactured by Burr-Brown, this can be used as a mic pre-amp with phantom power and 20dB pad and lots of gain, with less than 20 external components. the curcuit is simple, It shouldn't take more than an hour to make on veroboard)

These op-amps cost about $50NZ each ($1NZ = approx $0.58US)

Very nice Excen...superb, lol ;)

[Guest den_Juin]

Thanks for your reply rowan!

too bad i just ordered the SN74HC165N.

ah well, I'll just make another order.

[Rowan]

Hi

I've just ordered myself another 3 INA103KP's. I've got to wait till I order more so I can build the 8 channel mic pre I've been workink on.

Ian, how is the studio coming. If you haven't splashed out on multicore cable yet let me know. I'm on to a good deal for proel cable, I got some 12 core twisted pair on monday for $13/m, hey that's cheaper than 12 meters of single core from dick smith.

Very funny Xcen!! ::).....

Rowan, where did you get the circuit? are there any resources on the net for designing op-amp circuits, on a basic level that you know of??

bye, from Steve

[Nat]

Rowan : the 74HC165N will not work ???

[Rowan]

Hi

Nat: the IC may work, I haven't tried them.

Steven_C: Cheack out the Texes Inst. Page:

http://focus.ti.com/docs/prod/productfolder.jhtml?genericPartNumber=INA103  

Look At the data sheets. It will tell you all you need to know.

Hey Rowan,

Can you share your design of the mic pre,?

cause i read the data sheet but since I'm preety noob....

[Rowan]

Hi uclaros

If you download the datasheet pdf, a good simple design is featured in fig 12. I'm yet to test the design.

Power supply desing is VERY important with these type of circuits because any fluctations in the supply voltage will be imposed on the  audio output of the op amp.

When I get a chance I'll test it. I plan on intergrating these Mic pre's into the matrix I'm developing.
