A data-acquisition system on a chip

Multifunction data-acquisition systems have been around for a long time as stand-alone instruments, plug-in cards, cabled computer peripherals, and embedded in systems. Such systems are often designed with separate ADCs, DACs, and digital I/O devices. Many microcontrollers include ADCs and DACs, but that locks you into using that device. The AD5592R from Analog Devices combines all of these I/O functions, l ...

App note: Lithium ion battery charger using C8051F300

Introduction Driven by the need forunt ethered mobility and ease of use, many system srely on rechargable batteries as their primary power source. The battery charging circuitry for these systems is typically implemented using a fixed-function IC to control the charging current/voltage profile.The C8051F30x family provides a flexible alternative to fixed-function battery chargers. This application note disc ...

PD Buddy Sink – USB Power Delivery for everyone

Description USB Power Delivery is a cool standard for getting lots of power—up to 100 W—from a USB Type-C port. Being an open standard for supplying enough power to charge phones, laptops, and just about anything else under the sun, USB PD is poised to greatly reduce the amount of e-waste produced worldwide from obsolete proprietary chargers. Unfortunately, like all USB standards, it’s quite complex, puttin ...

Third version of homemade 6 GHz FMCW radar

Introduction Previously I made a simple frequency-modulated continuous-wave (FMCW) radar that was able to detect distance of a human sized object to 100 m. It worked, but as it was made with minimal budget and there was a lot of room for improvement. FMCW radar working principle If you have read my previous articles you should know how FMCW radar works, but for completeness sake short explanation is given b ...

I2C COMMUNICATION WITH PIC MICROCONTROLLER

I2C COMMUNICATION WITH PIC MICROCONTROLLER: I²C stands for Inter-Integrated Circuit. It is a short distance serial interface that requires only two bus lines for bi-directional data transfer. It is used for attaching lower speed peripheral ICs to microcontrollers in short distance communication. Low speed peripherals include external EEPROMs, digital sensors, lcd, etc. Page Contents 1 I2C communication PROT ...
