GENERAL DESCRIPTION
OUT B
The OP284 die is available only through this specification.
–IN A
90.6 mils
The OP284 is a dual operational amplifier, featuring a 4 MHz
bandwidth and rail-to-rail inputs and outputs. It is guaranteed
to operate in single-supply from 3 V to 36 V, or dual-supply
from ±1.5 V to ±18 V.
+IN A
This amplifier is superb for single-supply applications requiring
both ac and precision dc performance. The combination of
wide bandwidth, low noise, and precision makes the OP284
useful in a wide variety of applications, including filters and
instrumentation.
For application information, please refer to the OP284 package
product data sheet and webpage.

Limit the input current to less than 5 mA to prevent degradation or
destruction of the input devices.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
