The OPA234 series low cost op amps are ideal for  
single supply, low voltage, low power applications. The  
series provides lower quiescent current than older  
“1013”-type products and comes in current industry-  
standard packages and pinouts. The combination of low  
offset voltage, high common-mode rejection, high power  
supply rejection, and a wide supply range provides  
excellent accuracy and versatility. Single, dual, and  
quad versions have identical specifications for maxi-  
mum design flexibility. These general purpose op amps  
are ideal for portable and battery powered applications.

OPA234 series op amps operate from either single or  
dual supplies. In single supply operation, the input com-  
mon-mode range extends below ground and the output  
can swing to within 50mV of ground. Excellent phase  
margin makes the OPA234 series ideal for demanding  
applications, including high load capacitance. Dual and  
quad designs feature completely independent circuitry  
for lowest crosstalk and freedom from interaction.

Single version packages are 8-Pin DIP, SO-8 surface-  
mount, and a space-saving MSOP-8 surface-mount.  
Dual packages are 8-Pin DIP and SO-8 surface-mount.  
Quad packages are 14-Pin DIP and SO-14 surface-  
mount. All are specified for –40°C to +85°C operation.
