Single Supply Operation
The LT1013/1014 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— inad-
vertently or on a transient basis. If the input is more than
a few hundred millivolts below ground, two distinct prob-
lems 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
–
termi-
nal) to the input. This can destroy the unit. On the LT1013/
1014, the 400Ω resistors, in series with the input (see
schematic diagram), protect the devices even when the
input is 5V below ground.
