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.
