The op amp IC has become the universal analog IC because it can perform all analog tasks. OP AMPS FOR EVERYONE provides the theoretical tools and practical know-how to get the most from these versatile devices. This new edition substantially updates coverage for low-speed and high-speed applications, and provides step by step walkthroughs for design and selection of op amps and circuits.

* Modular organization allows readers, based on their own background and level of experience, to start at any chapter
* written by experts at Texas Instruments and based on real op amps and circuit designs from TI
* NEW: large number of new cases for single supply op amp design techniques, including use of web-based design tool
* NEW: complete design walk-through for low-speed precision op amp selection and circuit design
* NEW: updates, including new techniques, for design for high-speed, low distortion applications.
* NEW: extensive new material on filters and filter design, including high-speed filtering for video and data

Beware: The guide on how to calculate noise of op-amp amplifiers is full of errors, which resulted in great confusion as I tried to learn this topic and my calculations disagreed depending on which instructions I followed.
First big mistake: They combine the noise of the resistors with the *output* noise of the op-amp. Instead, they should be combining the noise of the resistors with the *input* noise of the op-amp, and then multiplying this by the gain to get the output noise.
Second big mistake: They sum the noise of multiple resistors together. Instead, they should be calculating the equivalent resistance seen by the source, and then using that. For instance, they combine a 10 MΩ resistor and a 100 kΩ resistor as if they were in series (10.1 MΩ), but they should be combining them as if they are in parallel (99 kΩ).
(These errors have since been confirmed by Art Kay, Senior Applications Engineer at TI).
There are also a number of other miscalculation/typo errors in this section, which makes me wonder how trustworthy the rest of the book is.
