Typical Application
The OPAx134 series operational amplifiers are unity-gain stable, and an excellent choice for a wide range of audio and general-purpose applications. All circuitry is independent in the dual version, maintaining normal behavior when one amplifier in a package is overdriven or short-circuited. Bypass the power supply pins with 10nF ceramic capacitors or larger to minimize power supply noise.
