The transfer function of this amplifier is: With R1 = R3 and R2 = R4, Equation 1 simplifies to This simplification can be a quick way to approximate the expected signal, but those resistors are never ...

Used to reject external interferences in low-power systems, single-chip difference amplifiers have for some time provided smaller, often-simpler alternatives to their discrete counterparts. Now, ...

Three low-power difference amplifiers are available that are as small as 4.9 mm x 3 mm; these amplifiers feature slew rates up to 10 times faster than competing products, it’s claimed. Designed for ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

We uncovered an audio myth on our YouTube channel I didn’t even know was being perpetuated by some esoteric amplifier companies. Apparently there is a belief that designing an amplifier to be too ...

And the primary difference between them is number of amps or amp power. So they can swap out the amp modules cheaply and charge extra for them, but they're not going to produce multiple versions of ...
