re: LTC2400 24-Bit ADC

   Ditto Marcos and Wagner's comments. I use two of them with a
precision external reference hooked up to a PIC. Very easy to program.
The results have been excellent. These are ideal for precision
voltmeters which is what I'm doing (2-channel with differential inputs).
Two status Bits provide Sign and Extended Range information which make
it easy to implement an auto-ranging DVM. There are other features such
as an internal oscillator, 110db 50/60Hz rejection, Auto Shutdown, 12.5%
Overrange and Underrange, reference voltage range of 0.1V to 0.9 x VCC,
and a 3-wire SPI interface. All this in a SO-8 package.
