Notes:

(1)Output voltage can be set up to 36 V even if the VCC is lower.

(2)Short-circuits from the output to VCC+ can cause excessive heating and potential destruction. The maximum

output current is approximately 20 mA independent of the magnitude of VCC+.

(3)Short-circuits can cause excessive heating. These values are typical.

(4)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ

resistor between two pins of the device. This is done for all couples of connected pin combinations while the other

pins are floating.

(5)Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two

pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected

pin combinations while the other pins are floating.

(6)Charged device model: all pins and package are charged together to the specified voltage and then discharged

directly to ground through only one pin. This is done for all pins.

Notes:

(1)The input common-mode voltage of either input signal voltage should not be allowed to go negative by more

than 0.3 V. The upper end of the common-mode voltage range is (VCC+) – 1.5 V, but either or both inputs can go

to 30 V without damage.
