The ADA4001-2 is a dual JFET amplifier that features low input bias current, low input voltage noise, low input current noise, and rail-to-rail output.
The combination of low offset, low noise, and very low input bias currents makes this amplifier especially suitable for high impedance sensor amplification and precise current measure-ments using shunts. The combination of dc precision, low noise, and fast settling time results in superior accuracy in medical instruments, electronic measurement, and automated test equipment. Unlike many competitive amplifiers, the ADA4001-2 maintains fast settling performance even with substantial capacitive loads. 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.
Fast slew rate and great stability with capacitive loads make the ADA4001-2 a perfect fit for high performance filters. Low input bias currents, low offset, and low noise result in a wide dynamic range of photodiode amplifier circuits. Low noise and low dis-tortion, high output current, and excellent speed make the ADA4001-2 a great choice for audio applications.
The ADA4001-2 is specified over the −40°C to +125°C extended industrial temperature range.
The ADA4001-2 is available in an 8-lead narrow SOIC package.
