ad594 application
hi
I use AD594 to amplify one J thermocouple .I study ad594 datasheet.but I didnt realize about one part of this datasheet.I send the picture of that part.in this picture two tracks come to pin 1,14 from thermocouple's pin. why does tracks connect together ? and also I didnt realize this paragraph that relate to the picture.
"Here the AD594/AD595 package temperature and circuit board are thermally contacted in the copper printed circuit board tracks under Pins 1 and 14."
what can I do to decreae noise for this circuit.I use one 100k resistor from positive lead of thermocouple to pin 1 and one 100nf cap from pin 1 to ground.does the value of them is correct??
can any one send me schematic and pcb for ad594 with Noise Suppression please.
by regards
