INTERSIL SELECTION GUIDE | INDUSTRIAL PROCESS CONTROL SOLUTIONS

Intersil’s Solutions for Industrial Process Control

Precision data acquisition solutions are required for a broad

range of Industrial applications. Programmable logic controllers

(PLC), distributed control systems (DCS), smart transmitters,

and general-purpose data acquisition are used in the majority

of these Industrial systems. These applications utilize various

types of sensors and feedback mechanisms to monitor and

control machine or system interactions by collecting, storing,

and analyzing data. Sensor data acquisition involves precision

measurement and processing of analog variables, such as

voltages and currents, where there is a need to sense very

small changes. Intersil’s broad portfolio of analog, power and

interface solutions makes it well positioned to deliver world class

solutions to Industrial customers. In this solutions brochure, you

will find outstanding solutions from Intersil for your current and

future Industrial systems.

Intersil Corporation is a global technology leader specializing

in the design and manufacture of high performance analog

semiconductors. Built on a solid foundation, with many years

of analog experience, Intersil is committed to developing

leadership solutions for the Industrial market. Over the past

several years, Intersil has heavily invested and will continue to

invest in robust technology capable of supporting the demanding

requirements of the Industrial market. Intersil’s proprietary 40V

precision silicon-on-insulator (SOI) bipolar process technology,

developed, specifically to target the Industrial market and the

growing portfolio of leadership precision amplifiers, are excellent

examples of this commitment.

Design Requirements Interview

Design Configuration

1

2

Simply enter your design requirements, such as input and output

voltage and current etc.

iSim automatically calculates optimum loop compensation and

calculates appropriate values for resistors and capacitors.

Design Verification by Remote Simulation

Summary, Download, Design & More

3

4

Your design is displayed in an Online Schematic, which allows you to test

your application in a virtual test bed. iSim allows AC, transient analysis.

Once the design has been verified, iSim generates a Bill of Materials

and a comprehensive design report including simulation results,

schematic and design data.
