Data Sheet

AD5940

2-wire conductivity sensor. The pH measurement indicates the

acidity or alkalinity of the solution and uses an external amplifier

for buffering purposes before conversion by the ADC.

SMART WATER/LIQUID QUALITY AFE

The features and flexibility of the AD5940 make the device ideal

for water analysis applications. These applications typically

measure pH, conductivity, oxidation/reduction, and temperature.

Figure 54 shows a simplified version of the AD5940 configured

to satisfy these measurement needs. The high power PA loop

can be used for the conductivity measurement. Figure 54 shows a

In this application, as shown in Figure 54, the data FIFO and

AFE sequence lend themselves to autonomous,

preprogrammed, smart water measurements.
