Here is a video from Texas Instruments describing how to measure stability when testing power supplies.
Here is a video from Texas Instruments describing how to test DC-DC power supplies. Measurement of ripple and transient noise of switching power supplies is described in detail.
A video tutorial on the benefits and pitfalls of using aluminum electrolytic capacitors. Learn how these capacitors degrade, and how their life cycle is proportional to the stresses you put them through.
Texas Instruments goes over regulator output-voltage accuracy, warning that feedback resistor tolerances have a high impact on the output accuracy and should be chosen with care.
As with all electronics components capacitors can never be ideal, there are always parasitic components that have to be considered as well. With capacitors the most prominent parasitics are Equivalent series resistance (ESR), and Equivalent series inductance (ESl). The video … Read more
Here’s is a video from Texas Instruments describing the inner workings of delta-sigma analog to digital converters. The DS ADC is broken down into it’s basic parts. The delta-sigma modulator and digital decimating filter are then discussed. Delta-sigma converters are … Read more
Texas Instruments describes bootloaders and what they are all about. A bootloader is a piece of code that allows new firmware to be loaded into a microcontroller without a dedicated programmer. All of our projects use a bootloader so you … Read more
Here is a video from Texas Instruments describing the differences in motor pre-drivers vs integrated drivers. Pre-drivers have all the control circuitry but the FETs are external, while in integrated drivers everything is on one IC. Because pre-drivers use external … Read more
Mouser is giving away the Texas Instruments FRAM MCUs for Dummies book. Hand over your personal details to Mouser if you’re willing, and they’ll send you the book. Could be fun. Via the forum. Thanks Chuckt!
