The OPA4132UA is a high speed FET-input Operational Amplifier provides high speed and excellent DC performance. The combination of high slew rate and wide bandwidth provide fast settling time. Quad version has identical specifications for maximum design flexibility. The OPAx132 operational amplifier is easy to use and free from phase inversion and overload problems often found in common FET-input operational amplifier. Input cascade circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range. The OPAx132 series of operational amplifier is stable in unity gain and provide excellent dynamic behaviour over a wide range of load conditions, including high load capacitance. Quad version feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
