3 Description
The OPAx132 series of FET-input operational
amplifiers provides highspeed and excellent DC
performance. The combination of high slew rate and
wide bandwidth provide fast settling time. 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 ideal for general-purpose, audio, data
acquisition and communications 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 common FET-input operational
amplifiers. Input cascode circuitry provides excellent
common-mode rejection and maintains low input bias
current over its 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
completely independent circuitry for lowest crosstalk
and freedom from interaction, even when overdriven
or overloaded.
Single and dual versions are available in 8-pin DIP
and SO-8 surface-mount packages. Quad is available
in 14-pin DIP and SO-14 surface-mount packages. All
are specified for –40°C to 85°C operation
