PRODUCT DESCRIPTION

TOP VIEW  
The AD842 is a member of the Analog Devices family of wide  
bandwidth operational amplifiers. This device is fabricated using  
Analog Devices’ junction isolated complementary bipolar (CB)  
process. This process permits a combination of dc precision and  
wideband ac performance previously unobtainable in a mono-  
lithic op amp. In addition to its 80 MHz gain bandwidth, the  
AD842 offers extremely fast settling characteristics, typically  
settling to within 0.01% of final value in less than 100 ns for a  
10 volt step.

AD842 is also appropriate for other applications such as high  
speed DAC and ADC buffer amplifiers and other wide band-  
width circuitry.  
APPLICATION HIGHLIGHTS  
The AD842 also offers a low quiescent current of 13 mA, a high  
output current drive capability (100 mA minimum), a low input  
voltage noise of 9 nV√Hz and a low input offset voltage (1 mV  
maximum).  
1. The high slew rate and fast settling time of the AD842 make  
it ideal for DAC and ADC buffers amplifiers, lines drivers  
and all types of video instrumentation circuitry.  
2. The AD842 is a precision amplifier. It offers accuracy to  
0.01% or better and wide bandwidth; performance previously  
available only in hybrids.  
The 375 V/µs slew rate of the AD842, along with its 80 MHz  
gain bandwidth, ensures excellent performance in video and  
pulse amplifier applications. This amplifier is ideally suited for  
use in high frequency signal conditioning circuits and wide  
bandwidth active filters. The extremely rapid settling time of  
the AD842 makes this amplifier the preferred choice for data  
acquisition applications which require 12-bit accuracy. The  
3. Laser-wafer trimming reduces the input offset voltage of  
1 mV max, thus eliminating the need for external offset  
nulling in many applications.  
4. Full differential inputs provide outstanding performance in  
all standard high frequency op amp applications where the  
circuit gain will be 2 or greater.  
5. The AD842 is an enhanced replacement for the HA2542.
