    Operational amplifiers are undoubtedly the easiest and best way of performing a wide range of linearfunctions from simple amplification to complex analog computation. The cost of monolithic amplifiers isnow less than $2.00, in large quantities, which makes it attractive to design them into circuits where theywould not otherwise be considered. Yet low cost is not the only attraction of monoli
