Claim 0:
1. A monolithic substrate differential pair the amplifier apparatus for use with a thermocouple including a thermocouple hot junction with a hot junction minus output and a hot junction positive output, and a thermocouple cold junction with a cold junction minus output and a cold junction positive output, comprising:
a first mounting substrate;
the thermocouple hot junction mounted on the first mounting substrate;
a ceramic isolation base mounted to the first mounting substrate;
the thermocouple cold junction mounted to the ceramic isolation base;
a silicon carbide monolithic substrate mounted to the ceramic isolation base; and
a differential pair circuit with a first silicon carbide negative positive negative transistor and a second silicon carbide negative positive negative transistor mounted in thermal sensitive proximity on the monolithic substrate.
