A/D converter

[Archiver]

Hello,

Can someone help me find a good A/D converter. I am looking for one that can go
down to 1mV, and interfaces with the stamp.

Thanks
AC

The TLC2543 is an excellent converter. Easy to program and has a 12-bit
output. If you need programming help let me know. Samples are available
from TI if you want to go to the trouble.

How hard is it to program?

You need a Linear Tech LTC2400, a 24 bit chip, to get in the mv range. On
their web site they have a BASIC Stamp connection example.

Not hard. Here's a sample.

Adread:
low cs
pause 10
shiftout SDATA, clk, msbfirst, [ADch<<8\12]
pause 10
shiftin sdi, clk, msbpre, [result\12]
high cs
goto counter
return

I think it has 7 channels, and you have to address each channel. If you get
one and are in need of help let me know off-line.

I'm using the AD7730 from analog devices with the BS2,it accepts low level
signals directly from a transducer and outputs a serial digital word.A
recommended layout is important for the PCB that houses the AD7730.
