The OPA337 and OPA338 series rail-to-rail output CMOS
operational amplifiers are designed for low cost and minia-
ture applications. Packaged in the new SOT23-8, the
OPA2337EA and OPA2338EA are Burr-Brown’s
smallest
dual op amps. At 1/4 the size of a conventional SO-8 surface
mount, they are ideal for space-sensitive applications.
Utilizing advanced CMOS technology, OPA337 and
OPA338 op amps provide low bias current, high-speed
operation, high open-loop gain, and rail-to-rail output
swing. They operate on a single supply with operation as
low as 2.5V while drawing only 525µA quiescent current.
In addition, the input common-mode voltage range in-
cludes ground—ideal for single-supply operation.
The OPA337 series is unity-gain stable. The OPA338
series is optimized for gains greater than or equal to five.
They are easy to use and free from phase inversion and
overload problems found in some other op amps. Excel-
lent performance is maintained as the amplifiers swing to
their specified limits. The dual versions feature completely
independent circuitry for lowest crosstalk and freedom
from interaction, even when overdriven or overloaded.

ABSOLUTE MAXIMUM RATINGS
(1)
Supply Voltage ................................................................................... 5.5V
Input Voltage
(2)
.................................................. (V–) –0.5V to (V+) +0.5V
Operating Temperature .................................................. –55°C to +125°C
Storage Temperature ..................................................... –55°C to +125°C
Junction Temperature ...................................................................... 150°C
Lead Temperature (soldering, 10s) ................................................. 300°C
NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum ratings for extended periods may degrade
device reliability. (2) Input signal voltage is limited by internal diodes
connected to power supplies. See text. (3) Short circuit to ground, one
amplifier per package.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
