Low Leakage Diodes


In circuit designs for sensor signal conditioning, the design engineer must protect the input section

from over current and over voltage conditions. Op amps, ADC analog inputs, analog multiplexers,

and [RS485] line receivers represent classes of devices that need protection. Often, the

manufacturers of such devices specify the acceptable input range for voltage, or, in the case of an

overvoltage condition, the allowable input current above which semiconductor or bonding wires

may be damaged.
