- The common JFET current-source in Figure 1a has average output impedance and depends heavily on the JFET's V P and I DSS variations. These manufacturing variations limit the initial accuracy of the current setpoint that the circuit can obtain ...Jul 22, 2021
- Clayton Grantham EDN A reference current source needs high accuracy, low temperature drift, and high output impedance. Available IC current sources come with some of these features. However, at current levels greater than 1 mA, their output ...Jun 10, 2019
- Maxwell Strange EDN Forget to turn off the ceiling fan in your bathroom? Install the simple timer in Figure 1. It's located out-of-sight in the fan unit, and you turn it on via the wall switch. The circuit costs virtually nothing, using junk ...Jul 4, 2018
- Petre Petrov Electronic Design Choosing between two widely available, multisourced ICs for the core of an inductorless dc-dc converter the NE555 timer and the LM386 audio amplifier requires a look at their key specifications and performance in ...Apr 6, 2016
- Jose Blanes EDN Rectifier circuits based on semiconductor diodes typically handle voltage levels that greatly exceed the diodes' forward-voltage drops, which generally don't affect the accuracy of the rectification process. However, the rectified ...Sep 30, 2015
- This Switch Mode Power Supply circuit use the IC from National Semiconductor has been producing and designing ICs for use in switch-mode power supplies for many years. The application of these devices is normally straightforward, helped by the ...Jan 6, 2011
- Rajkumar SharmaThis schematic is designed to operate with minimum of external components. This amplifier offers high quality performance at very low distortion. Project is based on National LM1875 IC. The IC is thermal and short circuit protected. Specifications ...Feb 25, 2010
- This year I’ve been going on a lot of bike rides with friends, sometimes on public roadways, sometimes after dark. My bike has a nine watt 500 some odd lumen headlight, which makes it easy to see where I’m going, and definitely makes me ...Nov 23, 2009
- joe The LED VU Meter was the height of late 80-s boombox technology. This instructable will build one out on the breadboard. Who doesn't like blinking lights.. You will need either the National Semiconductor LM3916 / LM3915 / LM3914 , 2 for ...Sep 1, 2008
- The circuit is based on application of National Semiconductor. First is constituted by three voltage regulators LM338 [IC1-2-3] connected `'in parallel' '. The each one regulator has the possibility of giving 5 A in his output. Also ...Apr 10, 2005
