The AD8512-EP is a dual-precision JFET amplifier that features input voltages exceed the maximum common-mode voltage low offset voltage, input bias current, input voltage noise, and range. input current noise. Fast slew rate and great stability with capacitive loads make the The combination of low offsets, low noise, and very low input AD8512-EP suitable for high performance filters. Low input bias currents makes these amplifiers especially suitable for high bias currents, low offset, and low noise result in a wide dynamic impedance sensor amplification and precise current range of photodiode amplifier circuits. Low noise and distortion, measurements using shunts. The combination of dc precision, high output current, and excellent speed make the AD8512-EP low noise, and fast settling time results in superior accuracy in a great choice for military communication applications. flight instruments, electronic measurement, and aviation The AD8512-EP is available in an 8-lead narrow SOIC_N package. equipment. Unlike many competitive amplifiers, the AD8512- The AD8512-EP is specified over a military temperature range EP maintains its fast settling performance even with substantial of −55°C to +125°C. Additional application and technical capacitive loads. Unlike many older JFET amplifiers, the information can be found in the AD8512 data sheet. AD8512-EP does not suffer from output phase reversal when
