DESCRIPTION  
MICRO-SIZE, MINIATURE PACKAGES:  
The OPA237 op amp family is one of Texas Instruments’  
MicroAmplifierseries 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 The quad version is  
obsolete.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.
