TheLM348/LM248 is a true quad LM741. It consists of four independent, high-gain, internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar
LM741 operational amplifier. In addition the total supply current for all four amplifiers is comparable to the supply current of a single LM741 type OP Amp. Other features include input offset currents and input bias current which are much less than those of a standard LM741. Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling.

conditions might be negligible. However, adding resistance can be very undesirable in high-power applications. One option in such cases is to replace the instantaneous connection of a mechanical switch with the more gradual transition offered by an electronic switch, such as a MOSFET. The MOSFET does add a bit of resistance (typically around 0.01 ohms), but the important factor is the MOSFET’s gradual transition from non-conductive to conductive. With the mechanical switch replaced by a MOSFET, the…
Kirchhoff's current law combined with Ohm's Law is used in nodal analysis. Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software is used for modeling of circuit operation. Many Colleges and Universities use this type of software for the teaching of electronics technician and electronics engineering programs because of its accuracy. Electronics simulation software engages the user by integrating them into the learning…
While Japan’s major electronics OEM’s have fallen on difficult business times, these two suppliers are performing very well. In terms of overall business and financial performance, the WSJ reports that both of these suppliers posted profits for the first nine months of their fiscal year’s, fueled by healthy demand for products. Murata is one of the largest providers of ceramic capacitors and wireless communications modules. TDK is a leading global supplier of electronic inductors. The WSJ points out…

source sensed the presence of the phone, and queried the device to determine whether or not it was wireless power enabled. The phone gave a valid response and configured itself for resonant wireless power transfer. Under the console, the source electronics turned on and began charging the phone wirelessly—with no need for a charging cradle, power cord, or especially accurate placement of the phone. Marin relaxed when he heard the recharging chime and focused his attention on the road ahead.…
Sudden increase or decrease in loads and starting of motors are the cause of internal voltage sags. Depending on the magnitude, duration of the voltage sag and sensitivity of equipment, severity of the voltage sag can be evaluated. The sensitive electronic equipment's are such as variable speed drive (VSD) controls, programmable logic controllers (PLC’s), motor starter, power supply controller etc. A. Voltage Sag Classification and Characterization In the grid system, voltage sag is considered as…
Final Research Update - Bimodal Tesla Coil Collin Matthews Advisor: Dr. Jovan Jevtic 5/21/2013 Abstract The Tesla coil, invented in the 1890s, has found applications in areas as varied as radio-technology, medical and industrial X-rays, electromagnetic pulse weapons, lightning simulators, education and entertainment. Since its creation many evolutions have occurred: spark gap, rotary spark gap, vacuum tube, and solid-state designs. When used as lighting simulator Tesla coils are only…
