Low Noise, High Voltage Instrumentation Amp Using JFET Precision Op Amps

Process control applications in noisy environment often require differential measurements

For high impedance sensors it is desirable to maintain the input characteristics of high end amplifiers

This often results in a “roll their own” instrumentation amplifiers using select high performance precision amplifiers

The advantage is the user has a great deal of flexibility in achieving the desired performance and cost tradeoffs

The disadvantage is CMRR is limited by the matching of the resistors

Intersil’s new 40V precision amplifiers are excellent choices for these applications

Temperature Sensors

Temperature is the most widely measured parameter in Industrial Controls• The four most common types are Thermocouple, RTD, Thermistor and

Integrated Circuits• Each sensor has different characteristics and care must be taken to

select the appropriate sensor for a given application• In all cases calibration is needed and the accuracy will be dependent

on the sensor conditioning circuitSensors Thermocouple RTD Termistor Integrated Silicon
