Christopher Dean, Texas Instruments Electronic Design By adding a digital potentiometer and ratiometric division to a voltage-reference IC's feedback loop, you can set the reference's output voltage using a digital code. Adjustable voltage ...

Anwar Sadat, Ph.D., Texas Instruments Incorporate USB Type-C into an existing platform at minimal cost while using just one device. The USB Type-C or USB-C connector interface offers a reversible cable, and a flippable plug, with power delivery of ...

Have you ever used the term UART only to be corrected by another engineer that it isn’t a UART but USART? In certain circumstances the interchangeability of these terms may be appropriate but in many cases it is in error. Let’s examine ...

Steven Xie, Analog Devices Analog Dialogue Introduction Successive-approximation analog-to-digital converters, called SAR ADCs due to their successive-approximation register, are popular for applications requiring up to 18-bit resolution at up to 5 ...

Garima Gupta and Joshan Abraham Electronic Design Designers now can take their existing accessory designs and make them Android Open Accessory (AOA) Protocol-compliant The use of Android-based mobile Internet devices (MIDs), tablets, and other ...

Digi-key Touchscreens integrated into an LCD (usually TFT) or as part of a PCB have become the de facto user interface for modern handheld devices. Based mostly on resistive and capacitive technology, these transparent or opaque surfaces replace ...

William Wong Electronic Design Serial ports have disappeared from PCs but are they really gone? The title may use an idiom that is obsolete, or at least out of vogue, but the idea is one embedded developers should remember. What may obviously be ...

WirelessHD WirelessHD is based on the 60-GHz technology originally developed by SiBEAM, which Silicon Image acquired in 2011. The original specification became WirelessHD. It is maintained and promoted by the WirelessHD Consortium, a special ...
