DESCRIPTION  
The OPA2234 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. Dual versions have identical  
specifications for maximum design flexibility. These general-purpose op amps are ideal for portable and  
battery-powered applications.  
The OPA2234 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 OPA2234 series ideal for demanding applications, including high load capacitance. Dual  
design features completely independent circuitry for lowest crosstalk and freedom from interaction.  
Single and dual packages are in an SO-8 surface-mount and are specified for 55°C to 125°C operation.
