DESCRIPTION
MICRO-SIZE, MINIATURE PACKAGES:
The OPA237 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, dual, and quad versions have identical
specifications for maximum design flexibility. They are
− Single: SOT23-5, SO-8
− Dual: MSOP-8, SO-8
− Quad: SSOP-16 (Obsolete)
LOW OFFSET VOLTAGE: 750µV max

WIDE SUPPLY RANGE:
ideal
for
single-supply,
battery-operated,
and
− Single Supply: +2.7V to +36V
− Dual Supply: +1.35V to +18V
LOW QUIESCENT CURRENT: 350µV max
WIDE BANDWIDTH: 1.5MHz
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.
AD PPLICATIONS
BATTERY-POWERED INSTRUMENTS
Single, dual, and quad 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. The quad version is
obsolete. MSOP-8 has the same lead count as a SO-8 but
half the size. The SOT23-5 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.
