Analog to Digital converter (ADC) is the most used hardware feature on a microcontroller. It takes in analog voltage and converts it to a digital value. Since microcontrollers are digital devices and work with the binary digit 1 and 0, it could not process the analog data directly. Thus, an ADC is used to take

Thanks to their high accuracy and fast load recovery time, the R&S®NGM200 power supplies are perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur, for example, when mobile communications devices

Texas Instrument’s USB Dedicated Charging Port Controller TPS2514 is specifically designed to implement the charging schemas mentioned below. An auto-detect feature monitors USB data line voltage and automatically provides the correct electrical signatures on D+ and D– data lines. Note that the chip datasheet never mentioned Samsung or Apple in particular apparently due to the copyright issues.

A basic open-source multi-GHz sampling oscilloscope for experimenters on a budget. Still a work-in-progress, with key pieces on separate PCBs, but showing bandwidths in the 7-8 GHz range with >= 100 GSa/s equivalent-time sampling, and around 500 k comparisons/second real time. So far. Note: this writeup is somewhat out of date, as it doesn’t cover

The MAXREFDES111# reference design from Maxim Integrated is a compact 24V input flyback-converter module that features 5V at 400mA output. Transformer selection is often the most difficult step in isolated power design. Multiple transformers (Wurth Electronics 750315847, HanRun HR041087, and Sumida 06343-T588) have been qualified for this design, simplifying the process of transformer selection. The reference design delivers a

With digital semiconductor technology driving system power supplies to lower voltages for higher performance and lower system power, sensitive analog sensor circuits face a growing problem. Much of the inherent noise created in the early stages of an analog sensor signal path is independent of the amplifier bias voltage, so using a higher bias voltage
