Hello Newsgroup,

my name is Gerry and I currently work with a group on our diploma project
(that's the final exam period of my school type). In this project we use the
MAX195 16bit analogue digital converter.

We have now the following problem:
We made a printed circuit board and control the MAX195 directly with a PIC
microcontroller (PIC16F877). The MAX195 converts the analogue signal
correctly, but nearly every 3 seconds (it seems to be a periodic process)
the converted voltage "jumps"(e.g. from 1,12568 to 1,13568), but the
analogue signal (which has to be converted) does not.

We clock out the data serially (after the conversion) by setting the SCLK
pin high and low (controlled by the microcontroller).

If anyone of you has experiences with this ADC please help us,
we are trying to solve that problem for weeks without any results,

Gerry
