Power Supply Configurations
The LT1715 has separate supply pins for the input and
output stages that allow flexible operation, accommodat-
ing separate voltage ranges for the analog input and the
output logic. Of course, a single 3V/5V supply may be used
by tying + V
The minimum voltage requirement can be simply stated as
both the output and the input stages need at least 2.7V and
the V
The following rules must be adhered to in any
configuration:
Although the ground pin need not be tied to system
ground, most applications will use it that way. Figure 1
shows three common configurations. The final one is
uncommon, but it will work and may be useful as a level
translator; the input stage is run from – 5.2V and ground
while the output stage is run from 3V and ground. In this
case the common mode input voltage range does not
include ground, so it may be helpful to tie V
Conversely, V
the above rules are not violated.

Input Voltage Considerations
The LT1715 is specified for a common mode range of
–100mV to 3.8V when used with a single 5V supply. A
more general consideration is that the common mode
range is 100mV below V
for this common mode limit is that the output still
