AD8512ARZ

Product Summary

The AD8512ARZ is a single-, dual-, and quadprecision JFET amplifier that features low offset voltage, input bias current, input voltage noise, and input current noise. The combination of low offsets, low noise, and very low input bias currents makes these amplifiers especially suitable for high impedance sensor amplification and precise current measurements 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 AD8512ARZ maintains the fast settling performance even with substantial capacitive loads. Unlike many older JFET amplifiers, the AD8512ARZ 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 AD8512ARZ 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 distortion, high output current, and excellent speed make the AD8512ARZ a great choice for audio applications. The AD8512ARZ is both available in 8-lead narrow SOIC and 8-lead MSOP packages. The AD8512ARZ can be applied in instrumentation, multipole filters, precision current measurement, photodiode amplifiers, sensors, and audio.
