ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
circuitry, a 240 Ω series resistor should be placed on the analog inputs.
If the analog inputs are being driven from alternative V
Transient currents of up to 100 mA do not cause SCR latch-up.
