GENERAL DESCRIPTION

military temperature range of −55°C to +125°C and is available

processed to MIL-STD-883B, Rev. C.

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.

Extended reliability PLUS screening is available, specified over

the commercial and industrial temperature ranges. PLUS

screening includes 168-hour burn-in, in addition to other

environmental and physical tests.

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 ±±.±1%, the AD712 is ideal as a

buffer for 12-bit digital-to-analog and analog-to-digital

converters and as a high speed integrator. The settling time is

unmatched by any similar IC amplifier.

The AD712 is available in 8-lead PDIP, SOIC_N, and CERDIP

packages.

PRODUCT HIGHLIGHTS

1. The AD712 offers excellent overall performance at very

competitive prices.

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

4±± V/mV ensure 12-bit performance even in high speed

unity-gain buffer circuits.

2. The Analog Devices, Inc. advanced processing technology

and 1±±% testing guarantee a low input offset voltage (3 mV

maximum, J grade). Input offset voltage is specified in the

warmed-up condition.

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

±°C to 7±°C. The AD712A is rated over the industrial tempera-

ture range of −4±°C to +85°C. The AD712S is rated over the

3. Together with precision dc performance, the AD712 offers

excellent dynamic response. It settles to ±±.±1% 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.
