Product Summary
The INA121U is an FET-input, low power instrumentation amplifier offering excellent accuracy. The versatile three-op amp design and very small size of the device make it ideal for a variety of general purpose applications. Low bias current (±4pA) of the device allows use with high impedance sources. The applications of the INA121UA include: (1)low-level transducer amplifiers bridge, rtd, thermocouple; (2)physiological amplifiers ecg, eeg, emg, respiratory; (3)high impedance transducers; (4)capacitive sensors; (5)multi-channel data acquisition; (6)portable, battery operated systems; (7)general purpose instrumentation.
