Revealing the Ideas behind Circuits Circuit Idea ? >> ! “Electronic circuitry is more art than science. Inventing novel electronic circuits is a result of human fantasy, imagination and enthusiasm. Fortunately, abstract electronic circuits are based on clear and simple ideas, which we may derive from our human routine. In order to really understand how circuits operate, we have first to reveal the basic ideas on which they are grounded…”

CA3140 and CA3130 are originally RCA part numbers( i feel). They are amazing close to ideal opamps, the input offset has to be trimmed. I used to use it when high input impedance is required. 1.5T ohm 10pA is the specs. A Electrometer can be made with just one opamp. CA3130 has the additional Merit of swinging to the rails, if you are on a +/- 12V supply, the output will be +/-12V. This is a feature required in control applications. CA3130 – “15MHz, BiMOS Operational Amplifier with MOSFET Input/CMOS Output A CMOS transistor-pair, capable of swinging the output voltage [Read More ....]
