LTC6078 pH Probe Amplifier

Aug 16th 2005
pH Probe amplifiers require buffer amplifiers with an input impedance greater than 10^13 ohms. Without loading the probe, an output of approximately 60mV/pH unit is produce. The thermistor is added to provide first order compensation for the inherent temperature coefficient of the pH probe output. ...
