Hi Per, hmm the CA3162 is an interesting chip, but spontaneously I would certainly not know where still to obtain it... I checked Ebay, though, and they are for sale @ 15EUR a piece. My ADCs from Maxim were cheaper as samples ;-) But I don't get something: You can use the chip for many input voltages with a coltage divider. But how does the chip "know" which is the original reference voltage?
OK, now here is the pictures I promised: http://www.jb-electronics.de/tmp/voltmeter_1.jpg http://www.jb-electronics.de/tmp/voltmeter_2.jpg http://www.jb-electronics.de/tmp/voltmeter_3.jpg And the c source: http://www.jb-electronics.de/tmp/voltmeter_source.c Looking forward to your criticism, Jens -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
