Texas Instruments OPAx237 MicroAmplifier™ Op Amps
Texas Instruments OPAx237 MicroAmplifier™ Operational Amplifiers (Op Amps) are small in size and 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 are ideal for single-supply, battery-operated, and space-limited applications, such as PCMCIA cards and other portable instruments.
The Texas Instruments OPAx237 can 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 within 10mV of the ground. Dual designs feature independent circuitry for the lowest crosstalk and freedom from interaction.
Single and dual versions are offered in space-saving surface-mount packages. The single version is available in the ultra-miniature 5-lead SOT23-5 and SO-8 surface mount. The dual version comes in a miniature MSOP-8 and SO-8 surface mount. MSOP-8 has the same lead count as an SO-8 but is half the size. The SOT-23-5 is even smaller at one-fourth the size of an SO-8. All are specified for -40°C to +85°C operation. A macro model is available for design analysis.
