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碌A(chǔ) per amplifier,
the OPA705 still offers excellent dynamic performance
(1MHz GBW and 0.6V/碌s SR) and unity-gain stability.
The OPA705 series is fully specified and guaranteed over
the supply range of
鹵2V
to
鹵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 鈥?0擄C to +85擄C.
