●Product Details
●The ADA4610-1/ADA4610-2/ADA4610-4 are precision junction field effect transistor (JFET) amplifiers that feature low input noise voltage, current noise, offset voltage, input bias current, and rail-to-rail output. The ADA4610-1 is a single amplifier, the ADA4610-2 is a dual amplifier, and the ADA4610-4 is a quad amplifier.
●The combination of low offset, noise, and very low input bias current makes these amplifiers 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/ADA4610-2/ADA4610-4 provide superior accuracy in medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, the ADA4610-1/ADA4610-2/ADA4610-4 maintain fast settling performance with substantial capacitive loads. Unlike many older JFET amplifiers, the ADA4610-1/ADA4610-2/ ADA4610-4 do not suffer from output phase reversal when input voltages exceed the maximum common-mode voltage range.
●The fast slew rate and great stability with capacitive loads make the ADA4610-1/ADA4610-2/ADA4610-4 ideal for high performance filters. Low input bias currents, low offset, and low noise result in a wide dynamic range for photodiode amplifier circuits. Low noise and distortion, high output current, and excellent speed make the ADA4610-1/ADA4610-2/ADA4610-4 great choices for audio applications.
●The ADA4610-1/ADA4610-2/ADA4610-4 are specified over the −40°C to +125°C extended industrial temperature range.
●The ADA4610-1 is available in an 8-lead SOIC package and in a 5-lead SOT-23 package. The ADA4610-2 is available in 8-lead SOIC, 8-lead MSOP, and 8-lead LFCSP packages. The ADA4610-4 is available in a 14-lead SOIC package and in a 16-lead LFCSP.
