GENERAL DESCRIPTION
The AD712-EP is a high speed, precision, monolithic
operational amplifier offering high performance over the
military temperature range of −55°C to +125°C. Its low offset
voltage and offset voltage drift are the results of advanced laser
wafer trimming technology. These performance benefits allow
the user to easily upgrade existing designs that use older
precision BiFET or bipolar op amps.
The superior ac and dc performance of this op amp makes it
suitable for active filter applications. With a slew rate of 16 V/μs
and a settling time of 1 μs to ±0.01%, the AD712-EP is ideal as a
buffer for 12-bit digital-to-analog converters (DACs) and 12-bit
analog-to-digital converters (ADCs) and as a high speed
integrator.

The combination of excellent noise performance and low input
current also make the AD712-EP useful for photodiode preamps.
Common-mode rejection of 88 dB and open-loop gain of
400 V/mV ensure 12-bit performance even in high speed unity-
gain buffer circuits.
The AD712-EP is available in an 8-lead SOIC_N package.
Additional applications information is available in the
