The OPA237 op amp family is one of Burr-Brown’s
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, dual, and quad versions
have identical specifications for maximum design flexibility.
They are ideal for single supply, battery operated,
and space-limited applications, such as PCMCIA
cards 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 independent
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 surface-
mount. The dual version comes in a miniature
MSOP-8 and SO-8 surface-mount. The quad is available
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°C to +85°C operation. A
macromodel is available for design analysis.
