Introduction and Stability

This section introduces the goals of the training series and provides a quick review of op amps with an intuitive look at the basic model of an op amp. We explore open loop gain, feedback, output impedance, and how the interaction of the three relate to stability. It is necessary to have a sound understanding of op amp stability fundamentals to understand the applications issues presented in the next section.

Modern Op Amps in Old School Designs

TI’s op amp specs are generally better than or equal to nearly all of the legacy part specs.  Whether your focus is on personal electronics, industrial or medical, every engineer interested in learning how to combat the problem of why our higher performance, lower cost op amps sometimes don’t work in legacy sockets should view this training. Learn from a training structured “definition by example”, based on real world cases to de-mystify these “TI doesn’t work in my legacy socket” occurrences.

Selection of Key Components (ADC, Signal Conditioning Amplifier) for AC Analog Input Module (AIM)

Fourth part of the session explains representation of Voltage or Current waveforms in Time and frequency domain and also looks at the customer use case for application of Time or frequency domain Analysis.

TI Precision Labs - Op Amps: Bandwidth

Did you know when calculating op amp bandwith you should always use the non-inverting gain?  Do you know why bandwidth impacts Iq?

In addition to answering those questions, we will show you nearly everything you ever wanted to know about op amp bandwidth including:

TI Precision Labs - Op Amps: Electrical Overstress (EOS)

Oops, what's that smell:  why did the "smoke test" fail?

This series covers the causes of electrical overstress and introduces several methods that can be used to improve and test circuit robustness against electrical overstress.  All of the examples in this series show op-amp circuits, but the methods used could be applied to other components as well.

TI Precision Labs - Op Amps: ESD

ZAP! Is your circuit protected against the thousands of volts which could be on your finger tips?

This series explains how electrostatic discharge, or ESD, can damage semiconductor components and what kind of internal protection circuitry is present in these devices.

TI Precision Labs - Op Amps: Input and Output Limitations

Have you ever experienced unexpected signal output behavior of an op amp, such as clipping or other non-linear behavior?

The cause of this may be either input common mode voltage limitations or output voltage swing restrictions.  Understanding data sheet specifications in the context of real world circuits will help you avoid experiencing this problem.  An inside look at an op amp's input and output stages on different process technologies provides additional insight.

TI Precision Labs - Op Amps: Input Offset Voltage and Input Bias Current

How well do you know the major contributors to DC op amp input errors?

TI Precision Labs - Op Amps: Noise

Did you know that a standard resistor component sitting upon your desk doing "nothing" is actually generating noise?

TI Precision Labs - Op Amps: Power and Temperature

How hot is too hot? Does my circuit need a heat sink?

Absolute maximum ratings and internal thermal protection schemes are also introduced.

TI Precision Labs - Op Amps: Slew Rate

True or False? A large and rapid voltage change in an op amp's output is always limited by the slew rate of the device.

If you think the answer is true, or you have seen output slew behavior you could not explain, this session is for you!  We will provide an explanation of large and small signal analysis, slew boost, slew rate over temperature, slew rate vs. full power bandwidth, and the relationship of Vos and slew rate.  In addition, an inside the op amp view of the cause of slew rate limit is presented.
