Op Amp Circuit Collection- National Semiconductor

This is a like a Opamp Design Quick Reference. All the generic configurations and also example designs help you start building the Analog Blocks for your Instrument, Equipment or Gadget. It would be ideal if you test out all the configurations on a breadboard. Then try building a Measurement device with demanding specs. A Micro-ohmmeter is a suggestion i would give for testing your skills.

Contact resistance of connectors is in micro-ohms. Here contact resistance can also be affected by contamination, thermoelectric EMF. One Amp of current is passed thru the specimen, a connector and the voltage measured. The measured voltage is in micro-volts, a small analog challenge. Sometimes the test current can be even 10 Amps pulsed and the voltage measured quickly. A sample and hold synced with the pulse has to be designed. The voltage sample is taken in the middle of the pulse. Build such things, that will build the analog skills. Remember the Real world is Analog.

Op amps for everyone – Ron Mancini

The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications.

Here is a PDF Version from Texas Instruments - Amplifiers & Linear
