ADA4610-1ARZ-R7

ADA4610-1ARZ-R7 is a low noise, precision, rail-to-rail output, JFET single channel opamp. The combination of low offset, noise, and very low input bias current makes this amplifier especially suitable for high-impedance sensor amplification and precise current measurements using shunts. With excellent DC precision, low noise, and fast settling time, the ADA4610-1 provides superior accuracy in medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, the ADA4610-1 maintains fast settling performance with substantial capacitive loads. Unlike many older JFET amplifiers, the ADA4610-1 does not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range. It is used in applications such as instrumentation, medical instruments, multipole filters, precision current measurement, photodiode amplifiers, sensors, and audio.
