OPA2234M - Low Power, Precision Single-Supply Operational Amplifiers

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.
