Linear designers who need high precision, low input bias current, low offset voltage, low offset voltage drift, low noise, and rail-to-rail input and output should know about the ADA4510. In precision signal chains, this IC is ideal for sensing, conditioning, and output drive.

Stepping up AC voltages is not uncommon, but when size and cost are key, discrete voltage multipliers can fit the bill. Voltage multipliers can be used in low-voltage analog and high-voltage, high-power industrial designs.

New integrated circuits for modern cars help design engineers integrate more effective engine control, augmented reality, and virtual reality systems that improve performance, fuel efficiency, comfort, and safety.

We’ll stay out of the analog-versus-digital debate. But we will review a versatile plug-and-play integrated audio system with available companion adapters that create a sound solution for all applications large and small in all types of venues.

The Analog Discovery 2 provides hours of technical enrichment to those who work with analog or digital circuits. For students, who are looking for programs that advance their knowledge in science, technology, engineering, and mathematics, it’s a pocket-sized tool that performs several functions.

These Analog Devices products enable students–even hobbyists–to learn more electrical engineering concepts in an interdisciplinary and applied approach while not in a classroom setting.

Using their analog expertise, ROHM Semiconductor has developed a new product line, the Nano Series, to achieve more compact parts that require less energy to operate.

Recently I attended the 137th Audio Engineering Society (AES) Convention in Los Angeles. If you aren’t familiar with the AES Convention it’s a small event that hosts a pro audio trade show along with a wide range of technical sessions for design engineers developing new audio products. This year the AES technical programs featured a product design track that covered networked audio, analog-to-digital (A/D) and Digital-to-Analog (D/A) design for high-resolution audio (HRA). Some of the best producers, recording engineers, and audio hardware designers in the world attend to participate in workshops and make themselves available for questions. If you’re designing products that include audio and have never attended the convention you might want to consider looking into next year’s convention.

I am going to share a trade secret with you today. Did you know you could read an analog signal even if you only have digital inputs on your microcontroller or single board computer? It used to be a common practice, but maybe not so much anymore, judging by the questions I have been asked recently. But you can, and all you need is a simple resistor and capacitor.
