INA128UA Datasheet

Instrumentation Amplifiers


The INA128UA and INA129 are low power, general purpose instrumentation amplifiers offering excellent accuracy. The versatile 3-op amp design and small size make them ideal for a wide range of applications.Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G = 100).A single external resistor sets any gain from 1 to 10,000.The INA128UA provides an industry-standard gain equation; the INA129 gain equation is compatible with the AD620. INA128UA Features • Low Offset Voltage: 50μV Max• Low Input Bias Current: 5na Max• High Cmr: 120db Min• Inputs Protected To ± 40v• Wide Supply Range: ± 2.25v To ± 18v• Low Quiescent Current: 700μA• 8-Pin Plastic Dip, So-8 INA128UA Applications • Bridge Amplifier• Thermocouple Amplifier• Rtd Sensor Amplifier• Medical Instrumentation• Data Acquisition
