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.
