The OPA337 and OPA338 series rail-to-rail output CMOS
operational amplifiers are designed for low cost and miniature
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 525mA quiescent current.
In addition, the input common-mode voltage range includes
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. Excellent
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.
