Easy to use analog output ; Temp range with 5V power: 0 to 1000℃ output (0 to 5VDC) as long as K type can handle it; Temp range with 3.3V power: 0 to 660℃ output (0 to 3.3VDC) as long as the K type can handle it ; AD8495 borad operating temp under 50°C ; Wiring: amplifier needs 0v and 5v pins to be connected to a power source, very small current requirements, so can just connect it to any 5v/3.3 and 0v pins on your controller board. This provides power to the board so it can do its amplifying. Signal output pin then needs to be connected to a spare analog input pin on your board. Look at your specific control board circuit diagram, find a pin that is currently unused that begins w/ a capital 'A'. These are usually available on expansion or auxiliary headers labelled AUX or EXP. LIKE, on a RAMPS board, you might use pin 'A3' which is located on header AUX-1. and you have to change the pin TEMP_0_PIN in your firmware. If you insist to plug the Signal output and gnd to thermistor port you have to desoldering the pullup resistor of that port.
