Quad, low bias current, low-noise, precision difet operational amplifier

The OPA130, OPA2130, and OPA4130 (OPAx130) series of

FET-input op amps combine precision dc performance

with low quiescent current. Single, dual, and quad

versions have identical specifications for maximum

design flexibility. OPAx130 are designed for general-purpose,

portable, and battery operated applications,

especially with high source impedance.

OPAx130 op amps are

easy to use and free from phase inversion and

overload problems often found in common FET-input

op amps. Input cascode circuitry provides

excellent common-mode rejection and maintains low

input bias current over the wide input voltage

range of the amplifier. OPAx130 series op amps are stable in unity

gain and provide excellent dynamic behavior over a

wide range of load conditions, including high load

capacitance. Dual and quad designs feature

completely independent circuitry for lowest

crosstalk and freedom from interaction, even when

overdriven or overloaded.

Single and dual versions are available in an

8-pin SOIC surface-mount package. The quad version

is available in a 14-pin SOIC surface-mount

package. All devices are specified for –40°C to

+85°C operation.
