    I ordered quad op-amps to cater for the 4 op amps in each filter but now there is a 5th op-amp for the buffer do I need to make this buffer circuit for every filter, also or can I use the the one buffer circuit for all of the reference ground on each and every filter as I will be using the same...

    help with IR2110 chips

    I thought someone would appreciate the circuit being reallised with the help of you guys, and to say I started from scratch learned half bridge and H-bridge the IR2110's bootstrapping mosfets and all that including spice I thought you'd be pleased to see that all the help was not in vein thats...

    can I use the TL074 for the buffer, and I think I understand it, do you use the same 12v going into the filters op-amps as the input for the buffer and then connect the refs together as you said before? also can you use this buffer for all of the filters or do you need to create a buffer for...

    that easy, just connect the points called ref, for the virtual, and then what about the part in the red box

    Sallen Key Low Pass Filter, bandpass filter

    From what I understand it is still possible to use the TL074's

    Ok what is a virtual ground reference point and can I use my TL074's

    Also if i were to use a battery with a voltage inverter to get the desired positive and negative could I use these voltages across all of the operational amplifiers or would I need to make the voltage circuit for all of the operational amplifiers?

    does the op-amp wizard tool work with the single supply operational amplifier?
