App note: Build precise S/H Amps for fast 12 Bit ADCs
An app note from Analog Devices: Build precise S/H Amps for fast 12 Bit ADCs (PDF!) S/h amplifier circuits will use one of several standard architectures: closed-loop or open-loop, and inverting or noninverting configurations. No matter what circuit type designers employ, they need to incorporate a high-speed amplifier to buffer the input signal and a […]
Free PCB Sunday: Pick your PCB
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week two random commenters will […]
App note: In house unit with bluetooth low energy module hardware user guide
In house unit with bluetooth low energy module hardware user guide (PDF): This document describes the design details of the In House Unit (IHU) project. It will guide the user to know and start the design based on this IHU board. It gives a clear concept of the entire design. The IHU design with CSR […]

App note: PWM Margining with the MAX34451
This application note outlines the performance of PWM margining when the MAX34451 is connected to the MAX15041 evaluation (EV) kit: Pulse-width modulation (PWM) margining is a simple technique to adjust the output voltage of power supplies. This application note discusses the effect of PWM on the power-supply output-voltage noise, the enabling and disabling of PWM, […]
App note: Practical guide to implementing Solar Panel MPPT Algorithms
An application note from Microchip: Practical guide to implementing Solar Panel MPPT Algorithms (PDF!) This application note describes how to implement MPPT using the most popular switching power supply topologies. There are many published works on this topic, but only a tiny portion of them show how to actually implement the algorithms in hardware, as […]

Get in touch with your things – Souliss
Get in touch with your things – Souliss: The future of lights goes through LEDs because compared to standard lights they’re tiny, easy to control and consume low power. But what we were missing until now was a powerful yet straightforward hardware controller for everyone willing to use LEDs and strips on Arduino compatible boards, […]
RGB LED driven by PWM using Netduino
Embedded-Lab is doing a series of tutorials for the Netduino. The Day 7 tutorial of a series is RGB LED color formation using Pulse Width Modulation: Pulse Width Modulation (PWM) is a digital method of delivering a varying amount of power to a load, and hence can be used to control the brightness of an […]
