TEMPERATURE-VOLTAGE CONVERTER Russian patent published in 2009 - IPC H01C17/22 G01R19/32 

FIELD: physics.

SUBSTANCE: temperature-voltage converter has an operational amplifier and two resistive voltage dividers, made using thin-film technology, the output of the first of which is connected to the non-inverting input of the operational amplifier. The output of the second voltage divider is connected to the inverting input. The input of the first resistive voltage divider is connected the output of the reference voltage source, and the input of the second - to the output of the operational amplifier. The voltage dividers are made as a separate chip assembly, in which between the terminal for connecting to the reference voltage source and the terminal for connecting to the inverting input of the operational amplifier, an additional resistor is connected, made using integrated technology and from the same material as the second voltage divider, with resistance equal to resistance of the negative feedback circuit of the operational amplifier.

EFFECT: increased reliability.
