DESCRIPTION
The OPA237 op amp family is one of Burr-Brown’s
Micro
Amplifier
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
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 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
°
C to +85
°
C operation. A
macromodel is available for design analysis.
