Industrial Applications
Programmable Logic Controllers – Analog Input

Common to all of these systems is the need for acquiring data from sensors, processing it and delivering an output to a control device.  This involves precision measurement and processing of analog variables, such as voltages and currents, where there is a need to often sense very small changes. The output signal in an industrial control system consist of usually multi-channel channel outputs that can be analog voltage output (3V, 5V, 10V, +/-5V, +/-12V, +/-15V) or current output [0 (4) mA – 20 (24) mA] for data acquisition processing.  The resolution of today’s analog outputs typically very between 12-bit to 16-bit accuracy and can vary from 2 to up to 64 channels in a very high density, small form-factor space. 

Intersil solutions today consist of a wide selection of precision, high voltage, low voltage op amps for output driving functions, voltage references, switch/muxes for signal routing and power solutions for loop control and precision DC regulation.  Check in the future for upcoming Intersil products.
