DESCRIPTION
The OPA130 series of FET-input op amps combine
precision dc performance with low quiescent current.
Single, dual, and quad versions have identical specifi-
cations for maximum design flexibility. They are ideal
for general-purpose, portable, 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
provides 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.

APPLICATIONS INFORMATION
V+
Trim Range: ±5mV typ
OPA130 series op amps are unity-gain stable and suitable
for a wide range of general-purpose applications. Power
supply pins should be bypassed with 10nF ceramic capaci-
tors or larger.

OPA130 op amps are free from unexpected output phase-
reversal common with FET op amps. Many FET-input op
amps exhibit phase-reversal of the output when the input
common-mode voltage range is exceeded. This can occur in
voltage-follower circuits, causing serious problems in
control loop applications. OPA130 series op amps are free
from this undesirable behavior. All circuitry is completely
independent in dual and quad versions, assuring normal
behavior when one amplifier in a package is overdriven or
short-circuited.

INPUT BIAS CURRENT
OPERATING VOLTAGE
The input bias current is approximately 5pA at room tem-
perature and increases with temperature as shown in the
typical performance curve “Input Bias Current vs Tempera-
ture.”
OPA130 series op amps operate with power supplies from
±2.25V to ±18V with excellent performance. Although
specifications are production tested with ±15V supplies,
most behavior remains unchanged throughout the full
operating voltage range. Parameters which vary signifi-
cantly with operating voltage are shown in the typical
performance curves.
Input stage cascode circuitry assures that the input bias
current remains virtually unchanged throughout the full
input common-mode range of the OPA130. See the typical
performance curve “Input Bias Current vs Common-Mode
Voltage.”
OFFSET VOLTAGE TRIM
Offset voltage of OPA130 series amplifiers is laser trimmed
and usually requires no user adjustment. The OPA130
(single op amp version) provides offset voltage trim con-
nections on pins 1 and 5. Offset voltage can be adjusted by
connecting a potentiometer as shown in Figure 1. This
adjustment should be used only to null the offset of the op
amp, not to adjust system offset or offset produced by the
signal source. Nulling offset that is not produced by the
amplifier will change the offset voltage drift behavior of
the op amp.
