    Description

    The OPA705 series low-cost op amps are optimized for applications requiring rail-to-rail input and output swing. Single, dual, and quad versions are offered in a variety of packages. While the quiescent current is less than 200A per amplifier, the OPA705 still offers excellent dynamic performance (1MHz GBW and 0.6V/us SR) and unity-gain stability.

    The OPA705 series is fully specified and guaranteed over the supply range of ±2V to ±6V. Input swing extends 300mV beyond the rail and the output swings to within 40mV of the rail.

    The single version (OPA705) is available in the MicroSIZE SOT23-5 and in the standard SO-8 surface-mount packages. The dual version (OPA2705) is available in the MSOP-8, SO-8, and DIP-8 packages.
