GENERAL DESCRIPTION
The SSM2135 dual audio operational amplifier permits excellent performance in portable or low power audio systems, with an operating supply range of 4 V to 36 V or ±2 V to ±18 V.
The unity-gain stable device has very low voltage noise of 5.2 nV/√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.
