Here is a close look at the common- versus differential-mode voltage and instrumentation amplifier (IA) topologies.

(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 ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

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 ...

The source that drives high-resolution analog-to-digital converters (ADCs) sees a high-frequency ac load and a dc load of a few hundred ohms or more. Thus, a high-performance op amp with high input ...

Analog Devices is offering a dual-channel, zero-drift operational amplifier which is a chopper-stabilised op amp designed for high DC precision and measurement stability. Suitable for use in gas ...

High performance with low power consumption: this requirement is coming to bear in more and more applications, especially when it comes to mobile, battery-operated devices. Particularly in the times ...
