DESCRIPTION

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

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

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.
