2. 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?

Understanding input voltage offset and input bias current specifications at room temperature are pretty straight forward.  However, what happens when the impact of temperature enters the picture?  How do you correctly interpret and apply the statistical distribution in datasheet graphs for these parameters to your overall error analysis?  You will walk away from this session with a thorough understanding of the two major contributors to DC op amp input errors:  input voltage offset (Vos) and input bias current (Ib).  We will go deeper than just the specifications and into how different input stage topologies and silicon process technologies impact Vos and Ib.

This video series covers op amp input voltage offset and input bias current theory, then applies it to a hands-on lab which includes TINA-TI circuit simulations and experimentation using a real circuit with test equipment.

3. 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?
