Dual Low Noise, Audio Amplifier

The LM833 is a standard low–cost monolithic dual general–purpose operational amplifier employing Bipolar technology with innovative high–performance concepts for audio systems applications. With high frequency PNP transistors, the LM833 offers low voltage noise (4.5 nV/ Hz ), 15 MHz gain bandwidth product, 7.0 V/µs slew rate, 0.3 mV input offset voltage with 2.0 µV/°C temperature coefficient of input offset voltage. The LM833 output stage exhibits no deadband crossover distortion, large output voltage swing, excellent phase and gain margins, low open loop high frequency output impedance and symmetrical source/sink AC frequency response.

The LM833 is specified over the automotive temperature range and is available in the plastic DIP and SO–8 packages (P and D suffixes). For an improved performance dual/quad version, see the MC33079 family.
