APPLICATION INFORMATION
The OPA615 operates from ±5V power supplies Power-supply bypass capacitors should be located as
(±6.2V maximum). Absolute maximum is ±6.5V. Do close as possible to the device pins. Solid tantalum
not attempt to operate with larger power supply capacitors are generally best. See Board Layout at
voltages or permanent damage may occur. the end of the applications discussion for further
suggestions on layout.
BASIC CONNECTIONS
Figure 39 shows the basic connections required for
operation. These connections are not shown in
subsequent circuit diagrams.
