The OPA130UAE4 is a low power precision FET-input Operational Amplifier combines precision DC performance with low quiescent current. Single version has identical specifications for maximum design flexibility. It is ideal for general-purpose and battery-operated applications, especially with high source impedance. OPA130 op amp is easy to use and free from phase inversion and overload problems often found in common FET-input op amp. Input cascade circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range. OPA130 series op amp is stable in unity gain and provides excellent dynamic behaviour over a wide range of load conditions, including high load capacitance.
