SSM2135SZ-REEL7

SSM2135 is a dual audio operational amplifier. The unity-gain stable device has very low voltage noise of 5.2nV/√Hz, and total harmonic distortion plus noise below 0.01% over normal signal levels and loads. Such characteristics are enhanced by wide output swing and load drive capability. A unique output stage permits output swing approaching the rail under moderate load conditions. Under severe loading, this device still maintains a wide output swing with ultralow distortion. Particularly well suited for computer audio systems and portable digital audio units, it can perform preamplification, headphone and speaker driving, and balanced line driving and receiving. It is used in applications such as multimedia audio systems, microphone preamplifiers, headphone drivers, differential line receivers, balanced line drivers, audio ADC input buffers, audio DAC l-V converters and filters, pseudo ground generators.
