So this tutorial should show you how to get an analog input using a PIC microcontroller (I’m using a PIC16f887) in assembly language. You may have a demo board (which makes programming way easier) just a chip. I’m using just a plain 40 pin chip on a breadboard. Step 1: Hardware Setup -You will need …

Digital electronics and Analog electronics doesn’t mix easily. A Microcontroller can’t get analog values unless an Analog-to-Digital converter is used, however, you may find a little complicated the use of an ADC and it need lots of Input/Output ports. Some Microcontrollers, like the small 8-pin Microchip PIC 12F675, do have an ADC integrated, but …

What is meant by Analog to Digital Converter (ADC)? An ADC converts analog signal to it’s corresponding digital signal. How to convert analog signal to digital signal? CircuitsGallery.com has already posted ADC using LM324 IC, in that ADC tutorial I had already explained Analog to Digital Converter how it works. While dealing with Microcontrollers we may …

Analog Devices, Inc. has announced the Power by Linear LTM4661, a low power step-up µModule regulator in a 6.25mm x 6.25mm x 2.42mm BGA package. Only a few capacitors and one resistor are required to complete the design, and the solution occupies less than 1cm²single-sided or 0.5cm²on double-sided PCBs. The LTM4661 incorporates a switching DC/DC controller, …

The AD7960 is an 18-bit, 5 MSPS charge redistribution successive approximation (SAR), analog-to-digital converter (ADC). The SAR architecture allows unmatched performance both in noise and in linearity. The AD7960 contains a low power, high speed, 18-bit sampling ADC, an internal conversion clock and an internal reference buffer. On the CNV± edge, the AD7960 samples the …
A few months ago I wrote a blog post about the chipKIT Basic I/O Shield and used Analog RBG Strips to demonstrate the the open drain FETs. This post is to give details on how to wire up the strip LEDs to the I/O Shield. You should already know how to program MPIDE before using …

Many times, designers are faced with the need of generating analogue or analog voltage levels in purely digital circuits. Although the market provides today a very broad range of dedicated digital-to-analogue converters, putting such a device in the schematic has a negative impact on the overall cost of the system. 1. Introduction In the first …
