Low Power, Precision

FET-INPUT OPERATIONAL AMPLIFIERS

DESCRIPTION

The OPA130 series of FET-input op amps combine precision

dc performance with low quiescent current. Single, dual, and

quad versions have identical specifications for maximum

design flexibility. They are ideal for general-purpose, por-

table, and battery operated applications, especially with high

source impedance.

OPA130 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. OPA130

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 designs

feature completely independent circuitry for lowest crosstalk

and freedom from interaction, even when overdriven or

overloaded.

Single and dual versions are available in DIP-8 and SO-8

surface-mount packages. Quad is available in DIP-14 and

SO-14 surface-mount packages. All are specified for

–40

°C to +85°C operation.
