The OPAx130 series of op amps are unity-gain stable and an excellent choice for a wide range of general-purpose applications. Bypass power supply pins with 10nF ceramic capacitors or larger.

The OPAx130 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. The OPAx130 series of op amps are free from this undesirable behavior. All circuitry is completely independent in dual and quad versions, and normal behavior can be expected when one amplifier in a package is overdriven or short-circuited.
