AD8512 Description

The AD8512 are dual-precision JFET amplifiers that feature 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 AD8512 maintain their fast settling performance even with substantial capacitive loads. Unlike many older JFET amplifiers, the AD8512 do 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 AD8512 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 AD8512 great choices for audio applications.

The AD8512 are both available in 8-lead narrow SOIC_N and 8-lead MSOP packages. MSOP-packaged devices are only available in tape and reel.

The AD8512 are specified over the −40°C to +125°C extended industrial temperature range.
