FET-INPUT OPERATIONAL AMPLIFIERS

DESCRIPTION

The OPA132 series of FET-input op amps provides high-

speed 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 communica-

tions applications, especially where high source impedance

is encountered.

OPA132 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 pro-

vides

excellent

common-mode

rejection

and

maintains low input bias current over its wide input voltage

range. OPA132 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 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.
