GENERAL DESCRIPTION

The AD845 conforms to the standard op amp pinout except

that offset nulling is to V+. The AD845J and AD845K grade

devices are available specified to operate over the commercial

0∞C to 70∞C temperature range. AD845A and AD845B

devices are specified for operation over the –40∞C to +85∞C

industrial temperature range. The AD845S is specified to oper-

ate over the full military temperature range of –55∞C to +125∞C.

Both the industrial and military versions are available in 8-lead

CERDIP packages. The commercial version is available in an

8-lead plastic mini-DIP and 16-lead SOIC; J and S grade chips

are also available.

The AD845 is a fast, precise, N channel JFET input, monolithic

operational amplifier. It is fabricated using Analog Devices’

complementary bipolar (CB) process. Advanced laser-wafer

trimming technology enables the very low input offset voltage

and offset voltage drift performance to be realized. This preci-

sion, when coupled with a slew rate of 100 V/ms, a stable unity

gain bandwidth of 16 MHz, and a settling time of 350 ns to

0.01%—while driving a parallel load of 100 pF and 500 W—

represents a combination of features unmatched by any FET

input IC amplifier. The AD845 can easily be used to upgrade

many existing designs that use BiFET or FET input hybrid

amplifiers and, in some cases, those which use bipolar input

op amps.

PRODUCT HIGHLIGHTS

1. The high slew rate, fast settling time, and dc precision of the

AD845 make it ideal for high speed applications requiring

12-bit accuracy.

The AD845 is ideal for use in applications such as active filters,

high speed integrators, photodiode preamps, sample-and-hold

amplifiers, and log amplifiers, and for buffering A/D and D/A

converters. The 250 mV max input offset voltage makes offset

nulling unnecessary in many applications. The common-mode

rejection ratio of 110 dB over a ±10 V input voltage range

represents exceptional performance for a JFET input high

speed op amp. This, together with a minimum open-loop

gain of 250 V/mV ensures that 12-bit performance is achieved,

even in unity gain buffer circuits.

2. The performance of circuits using the LF400, HA2520,

HA2522, HA2525, HA2620, HA2622, HA2625, 3550,

OPA605, and LH0062 can be upgraded in most cases.

3. The AD845 is unity gain stable and internally compensated.

4. The AD845 is specified while driving 100 pF/500 W loads.
