Product Summary

The INA114AU/1K is a low cost, general purpose instrumentation amplifier offering excellent accuracy. Its versatile 3-op amp design and small size make it ideal for a wide range of applications. A single external resistor sets any gain from 1 to 10,000. Internal input protection can withstand up to ±40V without damage. The applications of the INA114AU/1K include bridge amplifier, thermocouple amplifier, rtd sensor amplifier, medical instrumentation and data acquisition.
