1. All voltage values, except the differential voltage are with respect to the network ground terminal.
2. The differential voltage is a non-inverting input terminal with respect to the inverting input terminal. The
OA2MPA and OA4MPA devices include an internal differential voltage limiter that clamps internal
differential voltage at 0.5 V.
3. V_CC - V_in must not exceed 6 V, V_in must not exceed 6 V.
4. Input current must be limited by a resistor in series with the inputs.
5. Short-circuits can cause excessive heating and destructive dissipation.
6. R_th are typical values.
7. Human body model: 100 pF discharged through a 1.5 kresistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
8. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5 ), done for all couples of pin
combinations with other pins floating.
9. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to ground.
