Operational Amplifier FAQ
Q1:When using a multi-circuit op.amp incorporating 4 or 6 circuits, how should I treat the unused circuits?
Q2:How can I prevent an op.amp from oscillation?
Q3:If the input voltage of an op.amp exceeds operating voltage, is that a problem to use?
Q4:I cannot find the maximum output current on the data sheet.
Q5:The chart of "Voltage gain vs. phase frequency characteristics" shows all 40dB gain. Doesn't it also explain voltage gain Av figures?
Q6:How do I use the offset adjustment terminal of the op.amp and its adjustment range?
Q7:The input voltage goes down because the input impedance of the op.amp is low. How much is the real value of input resistance?
Q8:Is it possible to calculate differential input resistance?
Q9:What is the maximum output voltage and common-mode input voltage range at actual operating voltage?
Q10:Is it possible to use a single-supply op.amp with dual supply?
Q11:Is it possible to use a dual-supply op.amp with single supply?
Q12:Can I use op.amps at different voltage in positive and negative side?
Q13:Do you have op.amps that feature high-quality sound?
Q14:I am trying to configure an audio circuit using an op.amp. How can I minimise the noise?
Q15:When I configure an audio circuit using an op.amp, what has to be taken into consideration for Sound-guality optiming inoruer to indiuisual prefereuce?
Q16:I heard that New Japan Radio has developed new products using the dielectrically-isolated process(SOI).Is it compatible with audio systems?
Q17:What is the benefit of using switch-equipped op.amps such as the NJM2120 as a selector?
Q18:What kind of precautions should I take when using a voltage follower with stability?
Q1:How should I deal with an unused channel in a multi-channel comparator?
Q2:When I replace the NJM2901 with the NJM12901, I cannot get proper output voltage.Why is that?
