ADA4610-1ARJZ-R7

ADA4610-1 is a precision junction field effect transistor (JFET) amplifier that feature low input noise voltage, current noise, offset voltage, input bias current, and rail-to-rail output. It is a single amplifier with 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, this device provides superior accuracy in medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, this device maintains fast settling performance with substantial capacitive loads. The fast slew rate and great stability with capacitive loads makes the device ideal for high performance filters. It is used in applications such as instrumentation, medical instruments, multipole filters, precision current measurement, photodiode amplifiers, sensors, audio.
