•
•
•
•
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.
1
FET input: IB = 50 pA Maximum
Wide Bandwidth: 8 MHz
High Slew Rate: 20 V/µs
Low Noise: 8nV/√Hz (1 kHz)
Low Distortion: 0.00008%)
High Open-loop Gain: 130 dB (600-Ω load)
Wide Supply Range: ±2.5 to ±18V
Low Offset Voltage: 500 µV Maximum
Single, Dual, and Quad Versions
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.

7 Detailed Description
7.1 Overview
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.

7.3 Feature Description
The OPAx132 series of JFET operational amplifiers combine low noise and wide bandwidth with precision and
low input bias current to make them the ideal choice for applications with a high source impedance. The
OPAx132 is unity-gain stable and features high slew rate (±20 V/μs) and wide bandwidth (8 MHz).
7.4 Device Functional Modes
The OPAx132 has a single functional mode and is operational when the power-supply voltage is greater than 5 V
(±2.5 V). The maximum power supply voltage for the OPAx132 is 36 V (±18 V).

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The OPAx132 series operational amplifiers are unity-gain stable and suitable for a wide range of generalpurpose applications. Power supply pins should be bypassed with 10-nF ceramic capacitors or larger.
The OPAx132 series operational amplifiers are free from unexpected output phase reversal common with FET
operational amplifiers. Many FET-input operational amplifiers 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. The OPAx132 series of operational amplifiers 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.
8.1.1 Operating Voltage
The OPAx132 series of operation amplifiers operate with power supplies from ±2.5 V to ±18 V with excellent
performance. Although specifications are production tested with ±15 V supplies, most behavior remains
unchanged throughout the full operating voltage range. Parameters which vary significantly with operating
voltage are shown in the Typical Characteristics section.
8.1.2 Offset Voltage Trim
Offset voltage of the OPAx132 series of amplifiers is laser trimmed and usually requires no user adjustment. The
OPAx132 amplifier (single op amp version) provides offset voltage trim connections on pins 1 and 8. Offset
voltage can be adjusted by connecting a potentiometer as shown in Figure 18. This adjustment should be used
only to null the offset of the operational amplifier, not to adjust system offset or offset produced by the signal
source. Nulling offset could degrade the offset voltage drift behavior of the operational amplifier. While it is not
possible to predict the exact change in drift, the effect is usually small.

8.1.3 Input Bias Current
The FET-inputs of the OPAx132 series provide very low input bias current and cause negligible errors in most
applications. For applications where low input bias current is crucial, junction temperature rise should be
minimized. The input bias current of FET-input operational amplifiers increases with temperature as shown in
Figure 5.
The OPAx132 series may be operated at reduced power supply voltage to minimize power dissipation and
temperature rise. Using ±3 V supplies reduces power dissipation to one-fifth that at ±15 V.

Application Information (continued)
The dual and quad versions have higher total power dissipation than the single, leading to higher junction
temperature. Thus, a warmed-up quad will have higher input bias current than a warmed-up single. Furthermore,
an SOIC will generally have higher junction temperature than a DIP at the same ambient temperature because of
a larger θJA.
Printed-circuit-board layout can also help minimize junction temperature rise. Temperature rise can be minimized
by soldering the devices to the circuit board rather than using a socket. Wide copper traces will also help
dissipate the heat by acting as an additional heat sink.
Input stage cascode circuitry assures that the input bias current remains virtually unchanged throughout the full
input common-mode range of the OPAx132 series. See Figure 6.
8.2 Typical Application
The OPAx132 family offers outstanding dc precision and ac performance. These devices operate up to 36-V
supply rails and offer ultralow input bias current and input bias current noise, as well as 8-MHz bandwidth and
high capacitive load drive. These features make the OPAx132 a robust, high-performance operational amplifier
for high-voltage industrial applications with high source impedance.

9 Power Supply Recommendations
The OPAx132 is specified for operation from 5 V to 36 V (±2.5 V to ±18 V); many specifications apply from
–40°C to 85°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature
are presented in the Typical Characteristics.
CAUTION
Supply voltages larger than 36 V can permanently damage the device; see the
Absolute Maximum Ratings.
Place 10-nF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or highimpedance power supplies. For more detailed information on bypass capacitor placement, see the Layout
Guidelines.
10 Layout
10.1 Layout Guidelines
For best operational performance of the device, use good PCB layout practices, including:
• Noise can propagate into analog circuitry through the power pins of the circuit as a whole and operational
amplifier itself. Bypass capacitors are used to reduce the coupled noise by providing low-impedance power
sources local to the analog circuitry.
– Connect low-ESR, 10 nF ceramic bypass capacitors between each supply pin and ground, placed as
close to the device as possible. A single bypass capacitor from V+ to ground is applicable for singlesupply applications.
• Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective
methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes.
A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital
and analog grounds paying attention to the flow of the ground current. For more detailed information refer to
Circuit Board Layout Techniques, SLOA089.
• In order to reduce parasitic coupling, run the input traces as far away from the supply or output traces as
possible. If these traces cannot be kept separate, crossing the sensitive trace perpendicular is much better as
opposed to in parallel with the noisy trace.
• Place the external components as close to the device as possible. As shown in Layout Example, keeping RF
and RG close to the inverting input minimizes parasitic capacitance.
• Keep the length of input traces as short as possible. Always remember that the input traces are the most
sensitive part of the circuit.
• Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce
leakage currents from nearby traces that are at different potentials.
• Cleaning the PCB following board assembly is recommended for best performance.
• Any precision integrated circuit may experience performance shifts due to moisture ingress into the plastic
package. Following any aqueous PCB cleaning process, baking the PCB assembly is recommended to
remove moisture introduced into the device packaging during the cleaning process. A low temperature, post
cleaning bake at 85°C for 30 minutes is sufficient for most circumstances.
