Analog Devices’ attenuators are available in a broad range of architectures and form factors, giving designers the flexibility to select a part best aligns with their system requirements. The parts ...

Op amps are very high gain amplifiers with differential inputs and single-ended outputs. They are often used in high precision analog circuits, so it is important to measure their performance ...

Today’s electronic systems are becoming more and more complex, with an increasing number of power rails and supplies. To achieve optimum power solution density, reliability and cost, often system ...

Comparator ICs are designed to compare the voltages that appear at their inputs and to output a voltage representing the sign of the net difference between them. In a comparator circuit, if the ...

Q. I've just been reading datasheets of some recently released Analog Devices log amps and I'm still a little confused about what exactly a log amp does. A. You're not alone. Over the years, I have ...

Even with the widespread use of rail-to-rail single supply op amps, there is still often the requirement for dual rails (for example, ±15 V) to be generated from a single (positive) input power rail ...

A reconstruction filter is an important element for creating a clean, low jitter clock signal from a direct digital synthesizer (DDS). A reconstruction filter is used at the output of the DAC to ...

The thermocouple is a simple, widely used component for measuring temperature. This article provides a basic overview of thermocouples, describes common challenges encountered when designing with them ...

Low-dropout regulators (LDOs) are deceptively simple devices that provide critical functions such as isolating a load from a dirty source or creating a low-noise source to power sensitive circuitry.
