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 525µA quiescent current. In addition, the input common-mode voltage range includes ground—ideal for single-supply operation.

The OPA337 series is unity-gain stable.
