(Plastic package)
The MC3x172 series are dual bipolar operational
amplifiers offering both low consumption
(200 µA/Amp) and good speed (2.1 MHz, 2 V/µs).
Moreover, the input common mode range extends
down to the lower supply rail, allowing single
supply operation from +4 V to +44 V.

Latch-up immunity Class A
1. Either or both input voltages must not exceed the magnitude of VCC.
2. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
3. 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.
4. 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.
5. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
