Single Supply Operation
The LT1013/LT1014 are fully specified for single supply
operation, i.e., when the negative supply is 0V. Input
common mode range includes ground; the output swings
within a few millivolts of ground. Single supply operation,
however, can create special difficulties, both at the input
and at the output. The LT1013/LT1014 have specific circuitry
which addresses these problems.
At the input, the driving signal can fall below 0V—in-
advertently or on a transient basis. If the input is more
than a few hundred millivolts below ground, two distinct
problems can occur on previous single supply designs,
such as the LM124, LM158, OP-20, OP-21, OP-220,
OP
-
221, OP-420:
a) When the input is more than a diode drop below
ground, unlimited current will flow from the substrate
(V
terminal) to the input. This can destroy the unit. On
the LT1013/LT1014, the 400Ω resistors, in series with the
input (see Schematic Diagram), protect the devices even
when the input is 5V below ground.
