Accurate Power Monitoring with LTC2992

Linear Technology Corporation, now a part of Analog Devices, Inc., has recently placed on the market a power monitoring IC, LTC2992, which offers a wide-range, dual monitoring system for current, voltage, and power for 0-100 VDC rails. The IC is self-contained and does not need additional circuitry for functioning. Users get a variety of options for operating the LTC2992. For instance, they can derive power from a 3-100 VDC monitored supply, or from a 2.7-100 VDC secondary supply, or from the shunt Read more [...]

Why Do ICs Need Bypass Capacitors?

Any electronic design engineer will vouch for the necessity of supplementing integrated circuits on their PCB with bypass capacitors, although they may not understand the reason to do so very well. As a rule of thumb, engineers provide every IC with a 0.1µF ceramic capacitor next to its power pins in each circuit board they design. Along with proper PCB layout techniques, adding a bypass capacitor improves circuit performance and maximizes the efficacy of the ICs. The trouble lies with transition Read more [...]

How Does Switching Affect Semiconductors?

Even though ICs rule the world of electronics, the transistor does all the work. Within each IC are millions upon millions of transistors perpetually switching on and off so that the IC can carry out its intended functions. Even if one of the multitudes of transistors were to stop switching, the IC could lose part or all of its functionality. Circuits handling digital signals most often use transistors to switch from a high state to a low state and vice versa. It is usual to call a circuit point Read more [...]

Demystifying the A/D and D/A Converters

Analog and Digital Signals Analog signals represent a physical parameter in the form of a continuous signal. In contrast, digital signals are discrete time signals formed by digital modulation. Most natural signals, like human voice and other sounds are analog in nature. Traditionally, communication systems were based on analog systems. As demand for systems capable of carrying more information over longer distances kept soaring, the drawbacks of analog communication systems became increasingly Read more [...]

Microchips to be imbedded in pills?

Yes, it's true. Proteus Biomedical has announced that they will be launching a innovative product that imbeds microchips in pills so that patients can be monitored by their health care professionals and even their families. The purpose of the monitoring is to be sure that patients are taking their medications properly and on time and to also monitor a range of additional patient information including respiration rate, heart rate, temperature, sleep patterns and physical activity. It is estimated Read more [...]

Available Methods of Marking Semiconductors

Semiconductor Markings - Available Methods Traditionally, most components have two or three lines of identifying marks plus a company logo. Over time, the manufacturer codes have become more involved to incorporate a component's identification plus the complete history of the process. Early on, it was the military applications that required very specific markings and identification processes. Current package markings are a by-product of those military requirements. When a semiconductor is clearly Read more [...]

Op Amps – Then and Now

Op Amps – Then and Now Op amp is the commonly used name for operational amplifiers, which are widely used electronic components. Op amps are often seen on many surface equipment designs and logging tools. The name ‘operational amplifier’ comes from the use of such high gain amps in performing mathematical operations for analog computer operations and is said to have been coined in 1947. A lot of study was done in the field and the initial operational amplifiers, based on Read more [...]
