It is designed specifically for aerospace and defense applications. The circuit operates from a single power supply over a wide range of voltages. Low power supply drain is independent of the magnitude of the power supply voltage. In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply. • Large output voltage swing 0 V to (VCC+) - 1.5V October 2014 This is information on a product in full production.

Short-circuits from the output to VCC can cause excessive heating if VCC > 15 V. The maximum output current is approximately 40 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 2. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 3. This input current only exists when the voltage values applied on the inputs is beyond the supply voltage line limits. This is not destructive if the current does not exceed 5 mA as indicated, and normal output is restored for input voltages above -0.3 V. 4. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ 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 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. Table 2.

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 +32 V without damage.

This current is essentially constant, independent of the state of the output, so there is no change in the loading charge on the input lines. 3. Due to the proximity of external components, ensure that stray capacitance does not cause coupling between these external parts. Typically, this can be detected because this type of capacitance increases at higher frequencies. 6/13 DocID026931 Rev 1 RT2904WH Electrical characteristics Figure 2.
