This is a TMP01 Temperature-to-Frequency Converter circuit. Converting voltage to the frequency domain is another common method of transmitting analog information. This circuit uses monolithic voltage-to-frequency converters (VFCs) that has some advantages like low cost a robust, and has open-collector digital output. The important information is frequency, so it is immune to voltage drops and noise. The temperature data can […]

This is a AD596/AD597 J-K Thermocouple Signal Conditioner circuit. When operated with J and K type thermocouples, the AD596/AD597 can produce a temperature proportional output of 10 mV/°C. Thermocouples generate low level output voltages which are a function of both the reference or cold junction temperature and temperature being measured. The AD596/AD597 is used to compensate the cold junction temperature. […]
