  1. Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you may not think the same way. Because much of my ...

  2. Certain designs need a programmable-gain amplifier with a wide gain range and high accuracy and common-mode rejection. Usually, it's wise to exploit a programmable-gain instrumentation amplifier, such as an AD625 . Unfortunately, the gain range ...

  2. Microcontrollers Supply Texas Instruments TPS3700 TPS3701 TPS3710 TPS3890 TPS386000
    Voltage supervisors have provided analog voltage monitoring to digital circuits for decades. Texas Instruments released the original TL7705 in 1983; it consumed 1.8 mA, came in a plastic dual-inline package (PDIP) and you can still purchase it ...

  4. Supply Analog Devices ADP1874 ADP2441
    A switching regulator can be constructed either monolithically or via a controller. In a monolithic switching regulator, the respective power switches, usually MOSFETs, are integrated within a single silicon chip. With controllers, in addition to ...

  5. Electronic Design I must be kidding, right? No, I’m not. I’m just suggesting that we take another look at the old programming language known as BASIC. The language has a great deal going for it, particularly that it’s easy to ...

  6. Supply Linear Technology LTC2950-1 LTC2951-1
    Design Note 391 Introduction Handheld designers often grapple with ways to de-bounce and control the on/off pushbutton of portable devices. Traditional de-bounce designs use discrete logic, flip-flops, resistors and capacitors. Other designs ...

  7. EDN As much as we’d prefer to be able to use just unforced, natural convection cooling, many designs and installations simply cannot be cooled adequately by the low level and uncertainty of airflow that this low-cost, reliable approach ...

  8. Measurement Analog Devices ADXL1002 AD4000
    Condition monitoring is one of today’s core challenges in the use of mechanical facilities and technical systems in which, for example, motors, generators, and gears are used. Planned maintenance is becoming more and more important for ...
