This is a buffer circuit for TMP01 Temperature Sensor. The output of this sensor is a low impedance dc output voltage with a 5 mV/K temperature coefficient. This sensor can be used in multiple control and measurement applications. The buffered VPTAT voltage output can drive 500 µA into 50 pF (maximum). Here is the schematic diagram of the circuit: To […]

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. […]

Buffer amplifier is required by a typical pH probe to isolate its 10^6 to 10^9 ohm source resistance from external circuitry. Such an amplifier is shown in the following figure. The voltage error produced by the bias current and electrode resistance is minimized by the low input current of the AD795JR. To minimize leakage, we have to use guarding, shielding, […]
