In olden days, when op amps used ±15 V supplies and input/output signals were ±10 V, we had few problems with input/output limitations. Our op amps output impedance (Zo), small-signal AC impedance, ...

This application note discusses on the how operational amplifiers drive capacitive loads. To dig this topic deeper, simulations are shown as a way of presenting the data. This note will help engineers ...

In 2008, Bob Pease exchanged e-mails with Linear Technology’s Mark Thoren, me, and a few other friends. The subject was how an amplifier will oscillate if you put a capacitive load on it. Bob knew ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some ...

Though not difficult, driving a load from a voltage reference IC requires some attention. After determining the supply voltage and output voltage, various other design parameters need to be considered ...

Most load cells on the market use a cantilever outfitted with strain gages to measure loads. Such cells also need a bulky and expensive signal conditioner to make them useful. Engineers at Loadstar ...

There are a number of reasons why an engineer would want to “split” a voltage rail in their design. Sometimes parts of the circuit, like a sensor or an IC, require a bipolar supply. Other reasons are ...

As the world shifts toward sustainable transportation, electric vehicles (EVs) have emerged as a key solution to reducing greenhouse gas emissions. However, one major hurdle remains: efficient and ...
