3 Description
The OPA317 series of CMOS operational amplifiers
offer precision performance at a very competitive
price. These devices are members of the Zerø-Drift
family of amplifiers that use a proprietary
autocalibration technique to simultaneously provide
low offset voltage (90 μV maximum) and near-zero
drift over time and temperature at only 35 μA
(maximum) of quiescent current.
The OPA317 family features rail-to-rail input and
output in addition to near flat 1/f noise, making this
amplifier ideal for many applications, and much easier
to design into a system. These devices are optimized
for low-voltage operation as low as 1.8 V (±0.9 V)
and up to 5.5 V (±2.75 V).
The OPA317 (single version) is available in the
SC70-5, SOT23-5, and SOIC-8 packages. The
OPA2317 (dual version) is offered in the VSSOP-8
and SOIC-8 packages. The OPA4317 is offered in
the standard SOIC-14 and TSSOP-14 packages. All
versions are specified for operation from –40°C to
+125°C.
