GENERAL DESCRIPTION

The AD844 is a high speed monolithic operational amplifier

fabricated using Analog Devices’ junction isolated complemen-

tary bipolar (CB) process. It combines high bandwidth and very

fast large signal response with excellent dc performance. Although

optimized for use in current-to-voltage applications and as an

inverting mode amplifier, it is also suitable for use in many

noninverting applications.

The AD844 can be used in place of traditional op amps, but its

current feedback architecture results in much better ac perfor-

mance, high linearity, and an exceptionally clean pulse response.

This type of op amp provides a closed-loop bandwidth that is

determined primarily by the feedback resistor and is almost inde-

pendent of the closed-loop gain. The AD844 is free from the slew

rate limitations inherent in traditional op amps and other

current-feedback op amps. Peak output rate of change can be over

2000 V/µs for a full 20 V output step. Settling time is typically

100 ns to 0.1%, and essentially independent of gain. The AD844

can drive 50 Ω loads to ± 2.5 V with low distortion and is short

circuit protected to 80 mA.

The AD844 is available in four performance grades and three

package options. In the 16-lead SOIC (R) package, the AD844J is

specified for the commercial temperature range of 0°C to 70°C.

The AD844A and AD844B are specified for the industrial

temperature range of –40°C to +85°C and are available in the

REV. E
