ADA4001-2ARZ

ADA4001-2 is a dual channel JFET amplifier that features low input voltage noise and current noise, input bias current, and rail-to-rail output. The combination of low noise and low input bias current makes this amplifier especially suitable for high impedance sensor amplification. With low noise and fast settling times, the ADA4001-2 provides good accuracy for medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, the ADA4001-2 maintains fast settling performance even with substantial capacitive loads, and, unlike many older JFET amplifiers, the ADA4001-2 does not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range. Typical application includes instrumentation, medical instruments, multipole filters, precision current measurement, photodiode amplifiers and sensors.
