GENERAL DESCRIPTION
The AD712 is a high speed, precision, monolithic operational
amplifier offering high performance at very modest prices. Its
very 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 BiFETs and, in many cases, 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 is ideal as a
buffer for 12-bit digital-to-analog converters (DACs) and analog-
to-digital converters (ADCs) and as a high speed integrator.
The settling time is unmatched by any similar IC amplifier.
The combination of excellent noise performance and low input
current also make the AD712 useful for photo diode 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 is pinned out in a standard op amp configuration
and is available in seven performance grades. The AD712J and
AD712K are rated over the commercial temperature range of
0°C to 70°C. The AD712A is rated over the industrial tempera-
ture range of −40°C to +85°C. The AD712S is rated over the
military temperature range of −55°C to +125°C and is available
processed to MIL-STD-883B, Rev. C.

PRODUCT HIGHLIGHTS
1. The AD712 offers excellent overall performance at very
competitive prices.
2. The Analog Devices, Inc., advanced processing technology
and 100% testing guarantee a low input offset voltage (3
mV maximum, J grade). Input offset voltage is specified in
the warmed-up condition.
3. Together with precision dc performance, the AD712 offers
excellent dynamic response. It settles to ±0.01% in 1 μs and
has a minimum slew rate of 16 V/μs. Thus, this device is
ideal for applications such as DAC and ADC buffers that
require a combination of superior ac and dc performance.
