DESCRIPTION

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 525

µA 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.
