Integrated Circuits and Devices

The OP07 has very low input offset voltage, like 75 µV and low input bias current like 4 nA and is used in instrumentation applications in the domains of Process control and Test-Measurement.

These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage. They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents.

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.
