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.
