(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 ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

The three-op-amp instrumentation amplifier in Figure 1 is seemingly a simple configuration in that it uses a basic, decades-old operational amplifier to gain a ...

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., ...

Members can download this article in PDF format. In designing an input stage for an analog-to-digital converter (ADC), engineers choose a particular amplifier, assign a target gain, and note the ...
