The OPA132 series of FET-input op amps provides

high-speed and excellent dc performance. The combi-

nation of high slew rate and wide bandwidth provide

fast settling time. Single, dual, and quad versions have

identical specifications for maximum design flexibil-

ity. 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.

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

provides 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.

APPLICATIONS INFORMATION

V+

Trim Range: ±4mV typ

OPA132 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.

10nF

100kΩ

OPA132 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. OPA132 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.

OPA132

OPA132 single op amp only.

Use offset adjust pins only to null

offset voltage of op amp—see text.

FIGURE 1. OPA132 Offset Voltage Trim Circuit.

INPUT BIAS CURRENT

OPERATING VOLTAGE

The FET-inputs of the OPA132 series provide very low

input bias current and cause negligible errors in most appli-

cations. For applications where low input bias current is

crucial, junction temperature rise should be minimized. The

input bias current of FET-input op amps increases with

temperature as shown in the typical performance curve

“Input Bias Current vs Temperature.”

OPA132 series op amps operate with power supplies from

±2.5V 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.

The OPA132 series may be operated at reduced power

supply voltage to minimize power dissipation and tempera-

ture rise. Using ±3V supplies reduces power dissipation to

one-fifth that at ±15V.

OFFSET VOLTAGE TRIM

Offset voltage of OPA132 series amplifiers is laser trimmed

and usually requires no user adjustment. The OPA132

(single op amp version) provides offset voltage trim con-

nections on pins 1 and 8. 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 could degrade the offset

voltage drift behavior of the op amp. While it is not

possible to predict the exact change in drift, the effect is

usually small.

The dual and quad versions have higher total power dissipa-

tion 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 gener-

ally have higher junction temperature than a DIP at the same

ambient temperature because of a larger θ_JA. Refer to the

specifications table.

Circuit board layout can also help minimize junction tem-

perature rise. Temperature rise can be minimized by solder-

ing 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 OPA132 series. See the

typical performance curve “Input Bias Current vs Common-

Mode Voltage.”
