MULTISTAGE AMPLIFIER - MIT
Example, CD-CC voltage buffer: • Advantages – No capacitors needed – compact • Disadvantages – Bias point shared:constrains designs. – Bias shifts from stage to stage and can stray too far from center of range – Generally requires level shifting to bring signal back to center of range. 4.7 V 5.0 V 2.5 V 3.2 V Assumes V BE = 0.7 V ...

For µA741: If the supply voltages are +15V and –15V the amplitude of the output voltage without clipping is 14V typically (guaranteed is 12V). The maximum that an Op Amp can supply to a load is restricted.
