GENERAL DESCRIPTION  
The AD844A and AD844B are specified for the industrial  
temperature range of −40°C to +85°C and are available in the  
CERDIP (Q) package. The AD844A is also available in an 8-lead  
PDIP (N). The AD844S is specified over the military temperature  
range of −55°C to +125°C. It is available in the 8-lead CERDIP  
(Q) package. A and S grade chips and devices processed to  
MIL-STD-883B, Rev. C are also available.  
The AD844 is a high speed monolithic operational amplifier  
fabricated using the Analog Devices, Inc., junction isolated  
complementary bipolar (CB) process. It combines high band-  
width 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.  
PRODUCT HIGHLIGHTS  
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.  
1. The AD844 is a versatile, low cost component providing an  
excellent combination of ac and dc performance.  
2. It is essentially free from slew rate limitations. Rise and fall  
times are essentially independent of output level.  
This type of op amp provides a closed-loop bandwidth that is  
determined primarily by the feedback resistor and is almost  
independent 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.  
3. The AD844 can be operated from 4.5 V to 18 V power  
supplies and is capable of driving loads down to 50 Ω, as  
well as driving very large capacitive loads using an external  
network.  
4. The offset voltage and input bias currents of the AD844 are  
laser trimmed to minimize dc errors; VOS drift is typically 1  
μV/°C and bias current drift is typically 9 nA/°C.  
5. The AD844 exhibits excellent differential gain and  
differential phase characteristics, making it suitable for a  
variety of video applications with bandwidths up to 60 MHz.  
6. The AD844 combines low distortion, low noise, and low  
drift with wide bandwidth, making it outstanding as an  
input amplifier for flash analog-to-digital converters (ADCs).  
The AD844 is available in four performance grades and three  
package options. In the 16-lead SOIC (RW) package, the AD844J  
is specified for the commercial temperature range of 0°C to 70°C.
