DUAL/QUAD LOW NOISE OPERATIONAL AMPLIFIERS

Order this document by MC3378/D The MC3378/9 series is a family of high quality monolithic amplifiers employing Bipolar technology with innovative high performance concepts for quality audio and data signal processing applications. This family incorporates the use of high frequency PNP input transistors to produce amplifiers exhibiting low input voltage noise with high gain bandwidth product and slew rate. The all NPN 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 and sink AC frequency performance. The MC3378/9 family offers both dual and quad amplifier versions, tested over the automotive temperature range and available in the plastic DIP and SOIC packages (P and D suffixes). Dual Supply Operation: ±5. V to ±8 V 2 Low Voltage Noise: 4.5 nv/ Hz Low Input Offset Voltage:.5 mv Low T.C. of Input Offset Voltage: 2. µv/ C Low Total Harmonic Distortion:.2% High Gain Bandwidth Product: 6 MHz High Slew Rate: 7.
