BIOMEDICAL_INSTRUMENTATION_DIFFERENTIAL_AMPLIFIER

This differential amplifier uses the isolated high-impedance inputs of the CA3420 BiMOS op amp. Because the CA3240's input current is only 50 pA maximum, 10-MΩ resistors can be used in series with the input probes to limit the current to 2 μA under a fault condition.
