DESCRIPTION

The OPA337 and OPA338 series rail-to-rail output CMOS

operational amplifiers are designed for low cost and

miniature applications. Packaged in the SOT23-8, the

OPA2337EA and OPA2338EA are Texas Instruments’

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, the 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

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 5. 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.
