OPA2237

The OPA237 op amp family is one of Burr-Brown's MicroAmplifier^TM series of miniature products. In addi- tion to small size, these devices feature low offset voltage, low quiescent current, low bias current, and a wide supply range. Single, dual, and quad versions have identical specifications for maximum design flex- ibility. They are ideal for single supply, battery oper- ated, and space-limited applications, such as PCMCIA ards and other portable instruments.

OPA237 series op amps 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 to within 10mV of ground. Dual and quad designs feature completely indepen- dent circuitry for lowest crosstalk and freedom from interaction.

Single, dual, and quad are offered in space-saving surface-mount packages. The single version is available in the ultra-miniature 5-lead SOT-23-5 and SO-8 sur- face-mount. The dual version comes in a miniature MSOP-8 and SO-8 surface-mount. The quad is avail- able in an SSOP-16. The SSOP-16 has the same body size as an SO-8 with 16 leads, while the MSOP-8 has the same lead count as a SO-8 but half the size. The SOT-23-5 is even smaller at one-fourth the size of an SO-8. All are specified for -40 to +85 operation. A macromodel is available for design analysis.
