Power Integrations has announced its InnoSwitch-CP family of off-line CV/CC flyback switching ICs. The new devices incorporate a constant power output profile which, when paired with an adaptive-voltage protocol such as Qualcomm Quick Charge 3.0 or USB-PD, permits smart mobile device makers to optimize charging time across a range of products. Developers employing adaptive charging […]

Common emitter non-symmetrical gain – I have simulated in LTspice a very simple CE amplifier. There is no AC capacitor at the emitter It is a plain and simple CE emitter bias unbypassed with a gain of Av = -Rc / RE = 4.07. It turns out that, as input is a perfect 1V sine […]
Aluminum backed PCBs take the heat
When the thermal heat dissipation requirements of a design are very high, using an aluminum backed PCB is a highly effective solution. Aluminum backed designs are able to better translate thermal energy away from your design’s components and, therefore control the temperature of your design. Additionally, they are on the order of ten times more […]
LVDT interface chips work over extended temperature range
Microsemi Corporation, a provider of semiconductor solutions differentiated by power, security, reliability and performance, announced the availability of a new device in its recently launched family of sensor interface integrated circuits (ICs) based upon inductive sensing technology, the LX3302. As the newest addition to the industry’s first inductive sensor interface IC product family utilizing linear variable differential transformer […]

Why is unloaded buffer showing an offset? – I am using an AD8041 IC as a buffer for a 0.2 Vpp sinewave input at 1 kHz from the function generator. The circuit is set on an NI Elvis II+ board. The buffer is unloaded but there occurs some offset at the output of the buffer. […]
VCM vs VOUT plots for instrumentation amplifiers with two op amps
This article introduces the VCM vs. VOUT plot for an instrumentation amplifier with two operational amplifiers (op amps) and delivers a thorough treatment of this amplifier topology. Additionally, the internal node equations are derived and used to plot each internal amplifier’s input common-mode and output-swing limits as a function of the instrumentation amplifier’s common-mode voltage. […]
Troubleshooting analog circuits
While you may need to troubleshoot a circuit that used to work and now doesn’t, the emphasis here is how to troubleshoot a design when you have your first PCB made. While you may be fortunate and everything works perfectly first time, there is often a need for some troubleshooting with a new design. The […]

Amplifying DC voltage from 5V to 12V – I use an Arduino board with a 5V output supply but I Ineed to operate 12V motor. I know that I could connect the Arduino to a 12V power supply to solve the problem. But but I can’t do it for some of reason so I have to build […]
24 bit DAQ system-on-chip series from Analog Devices
Analog Devices, Inc. introduced a 24-bit data acquisition system-on-chip (SoC) series designed to improve the performance of protection, monitoring, and power quality measurement equipment used to manage transmission and distribution of electrical energy within smart grid systems. The AD7770 enables higher performance and smaller form factor protection relays, while the AD7771 enables power quality measurement […]
