VO ≈ 1.4VDC, RS=0Ω with VCC from 5V to 30V and over full input common-mode range (0VDC+ to VCC -1.5V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC -1.5, but either or both inputs can go to +32V without damage. 4. Short-circuits from the output to VCC can cause excessive heating and eventual destruction. The maximum output current is approximately 40mA independent of the magnitude of VCC. At values of supply voltage in excess of +15VDC, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. 5. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of coupling increases at higher frequencies. |
