The Tried-and-True Operational Amplifier: An Overview
Operational amplifiers are still an integral component of most electronic systems. Given the ubiquitous nature of the op amp, let us take a step back and review the elements of an operational amplifier and why it is still so useful in today’s electronics.
Can I Use an Op Amp as a Comparator?
Learn more about two common integrated circuits—operational amplifiers and comparators—and explore the possible pitfalls of using an operational amplifier as a comparator.
Zero-Drift Amplifiers: Taking the Good With the Bad
The use of zero-drift amplifiers continues to grow due to the superior DC precision that these devices offer. However, there is a downside to this performance—time domain limitations.
How Do I Eliminate Flicker Noise in My Amplifier Design?
While there are many different sources of noise within an operational amplifier, perhaps the most mysterious and frustrating noise source is what is known as flicker noise. How does one deal with this dominating, low-frequency noise? If 1/f noise is a big concern, then selecting a zero-drift amplifier is the best solution.
Understanding the Function of Analog-to-Digital (ADC) Drivers
As the name implies, Analog-to-Digital Converter (ADC) drivers are specialty amplifiers that are designed specifically to work alongside ADCs, including successive approximation, pipelined and delta-sigma based architectures. These specialty amplifiers are critical circuit components that enable the ADC to function at full performance.
Automotive-Qualified Products
The low-power and low-noise performance of our AEC-Q100-qualified amplifiers and comparators makes them excellent choices for automotive designs.
Software Tools
Do you need help calculating your signal chain noise budget? The signal chain signal-to-noise calculator tool provides a simple, intuitive and flexible full-noise analysis of your signal chain.
