DESCRIPTION

The OPA705 series low-cost op amps are optimized for appli-

cations 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 200

µA per amplifier,

the OPA705 still offers excellent dynamic performance

(1MHz GBW and 0.6V/

µs 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. The quad OPA4705 is available

in the TSSOP-14 and SO-14 packages. All are specified for

operation from –40

°C to +85°C.
