Description
The OP07 is a very high precision op-amp with an
offset voltage maximu m of 150µV.
Offering also low input current (1.8nA) and high
gain (400V/mV), the OP07C is particularly
suitable for instrumentation applications .

3. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
4. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins
of the device with no external series resistor (internal resistor < 5Ω). Done for all couples of pin
combinations with other pins floating.
5. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.
