Product Summary

The INA118PB is a low power, general purpose instrumentation amplifier offering excellent accuracy. Its versatile 3-op amp design and small size make the INA118PB ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (70kHz at G = 100). 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 INA118PB include bridge amplifier, thermocouple amplifier, rtd sensor amplifier, medical instrumentation and data acquisition.
