15_V_ELECTRONIC_THERMOMETER

An electronic thermometer design, useful in the range of -55℃ to 150'℃, is shown. The sensor, S1, develops a current that is proportional to absolute temperature. This is given the required offset and range expansion by the reference and op amp, resulting in a direct readout in either ℃ or °F.
