The ADA4001-2 is a dual channel JFET amplifier that features With fast slew rate and great stability under capacitive loads, the low input voltage noise and current noise, input bias current, ADA4001-2 is a good fit for filter applications. With low input and rail-to-rail output. bias currents and noise, it offers a wide dynamic range for photodi- The combination of low noise and low input bias current makes ode amplifier circuits. Low noise and distortion, along with this amplifier especially suitable for high impedance sensor high output current and excel ent speed, make the ADA4001-2 amplification. With low noise and fast settling times, the a great choice for audio applications. ADA4001-2 provides good accuracy for medical instruments, The ADA4001-2 is specified over the −40°C to +125°C extended electronic measurement, and automated test equipment. Unlike industrial temperature range. many competitive amplifiers, the ADA4001-2 maintains fast The ADA4001-2 is available in an 8-lead narrow SOIC package. settling performance even with substantial capacitive loads, and, 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.
