Rail-to-Rail Op Amps Feature Precision & Power Efficiency
Rail-to-Rail Op Amps Feature Precision & Power Efficiency
07.03.2017 · News
Linear Technology introduces the LTC6258/59/60 and LTC6261/62/63, single/dual/quad op amps, extending its line of power efficient, low noise, precision operational amplifiers. These devices are part of a family of power efficient op amps ranging from 1.3 MHz GBW product at 20 μA supply current to 720 MHz GBW product at 3.3 mA supply current...
Instrumentation amplifier is less sensitive to resistor mismatch
Instrumentation amplifier is less sensitive to resistor mismatch
06.03.2017 · Circuits
This Design Idea offers a new instrumentation-amplifier topology that improves ac CMR (common-mode rejection). Because it uses discrete amplifiers, you can customize it for the lowest power, price, noise, and supply voltage, depending on your application’s requirements...
TI unveils industry's smallest 12-V, 10-A DC/DC step-down power solution
TI unveils industry's smallest 12-V, 10-A DC/DC step-down power solution
06.03.2017 · News
Texas Instruments introduced a pair of 12-V, 10-A, 4-MHz step-down power modules that provide a power management solution that is 20 percent smaller than any other 10-A power module-based solution available today. The easy-to-use SWIFT TPSM84A21 and TPSM84A22 DC/DC modules integrate power MOSFETs, shielded inductors, input and output capacitors, and passives...
3A, 1MHz Buck Mode LED Driver with Integrated Voltage Limiting
3A, 1MHz Buck Mode LED Driver with Integrated Voltage Limiting
05.03.2017 · Circuits
The LT®3952 monolithic LED driver includes a 4 A, 60 V DMOS power switch, excellent for driving high current LEDs in buck mode. Among its many features is an input current sense amplifier, which can be leveraged to provide built-in LED voltage limiting in buck mode. In buck mode, the anode of the LED string...
Python is better than C! (Or is it the other way round?)
Python is better than C! (Or is it the other way round?)
05.03.2017 · Articles
If you have a quick Google for something like "Python vs. C," you will find lots of comparisons out there. Sad to relate, however, trying to work out which is the "best" language is well-nigh impossible for many reasons, not the least that it's extremely difficult to define what one means by "best" in the first place...

Voltage Controlled Oscillator: CRO3060A-LF Ideal for Low Noise Fixed Wireless Equipment
05.03.2017 · News
Z-Communications, Inc. announces a new VCO model CRO3060A-LF. The CRO3060A-LF operates at 3050 to 3070 MHz with a tuning voltage range of 0.5 to 4.5 Vdc. This innovative VCO features a spectrally clean signal of –115 dBc/Hz @ 10 kHz offset and a typical tuning sensitivity of 14 MHz/V...
Pulse generator corrects itself
Pulse generator corrects itself
02.03.2017 · Circuits
Using a shift register with parallel output is a common way to design a pulse generator with N inputs and pulsed outputs having a width of T/N. To keep the output pulses consecutive, you can use feedback from the last output to the first input. At power-on, such a circuit can have a random combination of logic zeros and ones, forming an undesired data content of the shift register...
E-trucks with overhead power lines to be tested on Autobahn
E-trucks with overhead power lines to be tested on Autobahn
02.03.2017 · News
The idea of overhead power lines for electric vehicles is not new – after all, in the railway industry it is rather common. For electric trucks, it also has been considered for a while. Now the German government plans to test the technology on public highways...
Cap-Drop Approach Implements Offline Power Supply for Light Loads
"Cap-Drop" Approach Implements Offline Power Supply for Light Loads
01.03.2017 · Circuits
Low-power applications such as e-meters (electricity or energy meters) often require a simple ac line-powered supply where a 3.3-V rail powers a microcontroller and charges a lithium-ion battery to 4.2 V. You can implement this with a mains-frequency power transformer or with a more complicated ac-dc (offline) power supply...
