TI Precision Labs - Op Amps: Fully Differential Amplifiers

This series on fully differential amplifiers will teach you the benefits of differential signaling over the standard single-ended signals.

How would you convert a single-ended signal from a sensor to a fully differential signal in order to drive an ADC?

In this series on fully differential amplifiers (FDA), you will learn the benefits of differential signaling over the standard single-ended signal. You will be introduced to a new integrated amplifier architecture called the fully differential amplifier that converts a single-ended signal to a fully differential signal. Also discussed is how the integrated architecture is superior to a differential amplifier constructed using discrete single-ended op amps.

This video will prepare you to analyze the relationship between an input signal, an FDA's gain configuration and its input and output range compliance which is critical when interfacing to an analog-to-digital converter (ADC). You will also learn how to properly compensate and stabilize an FDA and how to verify the amplifiers phase margin in SPICE using TINA-TI macromodels.
