Application Hints
Avoid reversing the power supply polarity; the device will fail.
Common-Mode
Input
common-mode voltage limit is one diode drop above the
negative supply voltage. Exceeding this limit on either input
will result in an output phase reversal. The positive
common-mode limit is typically 1V below the positive supply
voltage. No output phase reversal will occur if this limit is ex-
ceeded by either input.
Output Voltage Swing vs I
:
For a desired output voltage
swing the value of the minimum load depends on the positive
and negative output current capability of the op amp. The
maximum available positive output current, (I
), of the de-
vice increases with I
whereas the negative output current
(I
CL
) is independent of I
