● Low Noise

BENEFITS
● Insignificant Signal Loss/Error Voltage with High-Impedance Source
● Low Power Consumption (Battery)
● Maximum Signal Output, Low Noise
● High Sensitivity to Low-Level Signals

APPLICATIONS
● High-Impedance Transducer Amplifiers
● Smoke Detector Input
● Infrared Detector Amplifier
● Precision Test Equipment
