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 pro-  
vides excellent accuracy and versatility. Single, dual,  
and quad versions have identical specifications for  
maximum design flexibility. These general-purpose op  
amps are ideal for portable and battery-powered appli-  
cations.

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

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