AKM Semiconductor – Mixed-signal IC

“AKM – Asahi Kasei Microdevices designs and manufactures CMOS mixed signal integrated circuits for applications including audio, multimedia, data storage, and telecommunications.”

Semiconductor magnetoresistive element AKM Semiconductor

Other Products – Touchscreen Controllers, Clock Generators.

Semiconductor magnetoresistive element (SMRE)

“Since a Sn doped single crystal film InSb is used as a material for the sensing element, the element has excellent magnetoresistive temperature characteristics and very small neutral voltage temperature drift. This element is mainly used for detection of gear rotation.”

Principle of operation of Hall effect IC

Detects a magnetic field and output analog/digital(IC) signal proportional to the intensity of the magnetic field. used for non-contact type switches, rotation detection, and position detection.

The Hall effect IC consists of Hall element and signal conditioning circuitry to convert the Hall element output into a digital output.

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.

Intersil – Analog and Power Semiconductors

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.

iSim Online Designer

Advanced design tool for creating complex solutions, this is available both as a software download or an online app.

Capture schematic, view waveforms, perform application analysis and more. It is an interactive web-based design tool for selecting and simulating devices from Intersil’s broad portfolio. (power management devices and operational amplifiers.)

Remote Strain Gauge Reference Design

Remote Strain Gauge Reference Design

“Intersil’s applications engineer, Daniel Goodhew, presents the remote strain gauge reference design using Nextreme’s thermal energy harvester and Intersil’s low power, low noise chopper amplifier.”

History

The original 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.

My own analog design carrer (while in college) started with national semiconductor databooks and Intersil CMOS Hot ideas.

Automatic Integrated Circuit Modeling Spice

Automatic Integrated Circuit Modeling Spice Automatic Integrated Circuit Modeling Spice (AIM-Spice) is a version of SPICE, the most popular analog circuit simulator. AIM-Spice is a new version of SPICE running under the Microsoft Windows and Linux operating systems. AIM-Spice for Windows is capable of displaying graphically the results of a simulation in progress, a feature that allows the operator to terminate a run based on an instant information on intermediate simulation results. SPICE – The simulator was developed at the University of California, Berkeley, and was first released in 1972. Many scientists at Berkeley and other institutions contributed to the [Read More ....]

Analog Devices - Process Control

In my early learning/building days 80s/90s, Chips and Hybrids of Analog Devices and Burr Brown were very expensive and their performance was unquestionable. They made building sensitive and precision instruments easy for an Instrumentation design engineer. Process Control & Industrial Automation – Analog Devices Another brand that was good/expensive for analog was Datel-GE. Another GE company called Intersil made the best chip-solutions with cmos. They not only worked well, they were also affordable and had low power consumption. Isolated 12 bit Voltage input, using AD8275, AD7920, ADR392 to measure +/-10v ranges. Includes Power Management solution. Programmable Logic Controllers – Distributed [Read More ....]

“There is a long gap between engineering college and mid career in a non-engineering position, but technology marches on so a simple method of keeping abreast with the latest developments is required. This application note starts with an overview of the basic laws of physics, progresses through circuits 1 and 2, and explains op amp operation through the use of feedback principles.” Basic Analog for Digital Designers – Application Note AN9510.2 October 19, 2004 This is an Analog Reference for the Embedded Engineer. An Application Note from Intersil Tech Reference.
