Intersil’s products include amplifiers, analog front ends, communication interfaces, data converters, digital potentiometers, display solutions, DSL solutions, optical storage products, power management products, real time clocks, switches/MUX’s, etc. In 2017 Intersil became a part of Renesas.
Intersil has developed into a leading analog semiconductor manufacturer with five specialized product groups: Consumer Power, Consumer Electronics, Analog Mixed Signal, Industrial Communications and Automotive & Military/Space Specialties.
Intersil was founded in 1967. After being acquired by General Electric Corp in 1981, it was sold to Harris Corporation in 1988, at which point the name was retired. Intersil at Wikipedia.
Since 1978, Wenzel Associates has defined the state-of-the-art in ultra-low phase noise while providing system manufactures with the highest quality, cost effective frequency components and instruments.
Wenzel Associates introduced the Blue Tops system building blocks to offer oscillator users well-characterized, low noise components, which improved the time to market for new frequency based systems.
Spice-based simulator for system design. It simulates complex mixed-signal designs containing both analog and digital parts, and it supports a wide range of simulation models such as IGBTs, pulse width modulators, DACs, and ADCs.
Schematic design solution, supporting both flat and hierarchal designs from the simplest to the most complex. Seamless bi-directional integration with OrCAD PCB Editor enables data synchronization and cross-probing/placing between the schematic and the board design.
This site contains a complete on-line tutorial for a typical bottom-up design flow using CADENCE Custom IC Design Tools (version 97A). The examples were generated using the HP 0.6 um CMOS14TB process technology files, prepared at North Carolina State University (NCSU) and made available through MOSIS.
The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.
The LF198, LF298, LF398 are monolithic sample-and-hold circuits which utilize BI-FET technology to obtain ultra-high dc accuracy with fast acquisition of signal and low droop rate. Operating as a unity gain follower, dc gain accuracy is 0.002% typical and acquisition time is as low as 6 µs to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offset adjust is accomplished with a single pin, and does not degrade input offset drift.
The wide bandwidth allows the LF198 to be included inside the feedback loop of 1 MHz op amps without having stability problems. Input impedance of 1010Ohm allows high source impedances to be used without degrading accuracy.
P-channel junction FET’s are combined with bipolar devices in the output amplifier to give droop rates as low as 5 mV/min with a 1 µF hold capacitor. The JFET’s have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities. The overall design guarantees no feed-through from input to output in the hold mode, even for input signals equal to the supply voltages.
National Semiconductor was an American semiconductor manufacturer, that specialized in analog devices and subsystems, formerly headquartered in Santa Clara, California, USA. The products of National Semiconductor included power management circuits, display drivers, audio and operational amplifiers, communication interface products and data conversion solutions.
The LMH0356 Serial Digital Interface (SDI) reclocker is designed to recover a clean clock from a serial digital video signal which may be contaminated by jitter and to resynchronize the input video data to the recovered clean clock. The LMH0356 SDI reclocker accepts signals conforming to standards SMPTE 259M (C), SMPTE 292M, and SMPTE 424M.
