Product Summary

The INA141U is a low power, 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. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100). The applications of the INA141U include bridge amplifier, thermocouple amplifier, RTD sensor amplifier, medical instrumentation and data acquisition.
