Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Picking a low-noise op amp is easier than ever, yet somehow harder also. How can this be? Harder – Because there are so many devices to choose from and the noise data is not always presented in the ...

(Editor's note: the op amp is a basic building block of the analog world and analog circuitry. Despite its extremely simple functional block diagram, it has many operating parameters from critical to ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

Switzerland-based STMicroelectronics (ST) has announced on March 9 its TSU111H 5V automotive operational amplifier with micro-power current consumption and 150°C operating-temperature capability.
