3 Description

The OPAx237 op amp family is one of Texas Instruments’ MicroAmplifier series of miniature products. In addition to small size, these devices feature low offset voltage, low quiescent current, low bias current, and a wide supply range. Single, and dual versions have identical specifications for maximum design flexibility. These devices are designed for single-supply, battery-operated, and space-limited applications, such as PCMCIA cards and other portable instruments.

The OPAx237 series op amps operate from either single or dual supplies. When operated from a single supply, the input common-mode range extends below ground and the output can swing to within 10mV of ground. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.

Single, dual, and quad versions are offered in space-saving surface-mount packages. The single version is available in the ultra-miniature 5-lead SOT23-5 and SOIC-8 surface-mount packages. The dual version comes in miniature VSSOP-8 and SO-8 surface-mount packages. The quad version is obsolete. The VSSOP-8 has the same lead count as a the SO-8, but at half the size. The SOT23-5 is even smaller, at one-fourth the size of an SOIC-8. All are specified for –40°C to +85°C operation. A macromodel is available for design analysis.
