GENERAL DESCRIPTION
The AD8510/AD8512/AD8513 are single-, dual-, and quad-
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 AD8510/
AD8512/AD8513 maintain their fast settling performance even
with substantial capacitive loads. Unlike many older JFET
amplifiers, the AD8510/AD8512/AD8513 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
AD8510/AD8512/AD8513 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 AD8510/AD8512/AD8513 great choices for audio
applications.
The AD8510/AD8512 are both available in 8-lead narrow SOIC_N
and 8-lead MSOP packages. MSOP-packaged parts are only
available in tape and reel. The AD8513 is available in 14-lead
SOIC_N and TSSOP packages.
The AD8510/AD8512/AD8513 are specified over the −40°C to
+125°C extended industrial temperature range.
