3 Description
The OPA132, OPA2132, and OPA4132 (OPAx132) series of FET-input operational amplifiers provides high speed and excellent dc performance. The bination of high slew rate and wide bandwidth provide fast settling time. The single, dual, and quad versions have identical specifications for maximum design flexibility. High-performance grades are available in the single and dual versions. All are an excellent choice for generalpurpose, audio, data-acquisition, and munications applications, especially where high source impedance is encountered.
The OPAx132 operational amplifiers are easy to use and free from phase inversion and overload problems often found in mon FET-input operational amplifiers. Input cascode circuitry provides excellent mon-mode rejection and maintains low input bias current over the wide input voltage range. The OPAx132 series of operational amplifiers are stable in unity gain and provide excellent dynamic behavior over a wide range of load conditions, including high load capacitance. Dual and quad versions feature pletely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
The single version is available in 8-pin SOIC surface mount package, the dual version is available in 8-pin DIP and SOIC surface-mount packages. The quad version is available in...
