Texas Instruments' OPA2234 low-cost op amp is ideal for single-supply, low-voltage, low-power applications. This device provides lower quiescent current than older “1013”-type products and comes in current industry-standard 8-SOIC package. 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 op amp operates 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.
