Low input bias currents, low offset, and low field effect transistor (JFET) amplifiers that feature low input noise noise result in a wide dynamic range for photodiode amplifier voltage, current noise, offset voltage, input bias current, and rail-to- circuits. Low noise and distortion, high output current, and rail output. The ADA4610-1 is a single amplifier, the ADA4610-2 is excellent speed make the ADA4610-1/ADA4610-2/ ADA4610-4 a dual amplifier, and the ADA4610-4 is a quad amplifier. great choices for audio applications. The combination of low offset, noise, and very low input bias The ADA4610-1/ADA4610-2/ADA4610-4 are specified over current makes these amplifiers especially suitable for high the 40C to +125C extended industrial temperature range. impedance sensor amplification and precise current measurements The ADA4610-1 is available in an 8-lead SOIC package and in a using shunts. With excellent dc precision, low noise, and fast 5-lead SOT-23 package. The ADA4610-2 is available in 8-lead settling time, the ADA4610-1/ADA4610-2/ADA4610-4 provide SOIC, 8-lead MSOP, and 8-lead LFCSP packages. The ADA4610-4 superior accuracy in medical instruments, electronic measurement, is available in a 14-lead SOIC package and in a 16-lead LFCSP. and automated test equipment. Unlike many competitive amplifiers, the ADA4610-1/ADA4610-2/ADA4610-4 maintain Table 1. Related Precision JFET Operational Amplifiers fast settling performance with substantial capacitive loads.
