80MHz, High Slew Rate, High Output  
Current, Video Operational Amplifier  
Features  
• Stable at Gains of 2 or Greater  
The HA-2842 is a wideband, high slew rate, operational  
amplifier featuring an outstanding combination of speed,  
bandwidth, and output drive capability. This amplifier’s  
performance is further enhanced through stable operation  
down to closed loop gains of +2, the inclusion of offset null  
controls, and by its excellent video performance.

• Low Supply Current (Max) . . . . . . . . . . . . . . . . . . . . 15mA  
• Enhanced Replacement for AD842  
The capabilities of the HA-2842 are ideally suited for high  
speed cable driver circuits, where low closed loop gains and  
high output drive are required. With a 6MHz full power  
bandwidth, this amplifier is well suited for high frequency  
signal conditioning circuits and video amplifiers. Gain  
flatness of 0.035dB, combined with differential gain and  
phase specifications of 0.02%, and 0.03 degrees,  
respectively, make the HA-2842 ideal for component and  
composite video applications.  
Applications  
• Pulse and Video Amplifiers  
• Wideband Amplifiers  
A zener/nichrome based reference circuit, coupled with  
advanced laser trimming techniques, yields a supply current  
with a low temperature coefficient and low lot-to-lot variability.  
• Coaxial Cable Drivers  
• Fast Sample-Hold Circuits  
• High Frequency Signal Conditioning Circuits

For example, the average I  
variation from 85 C to -40 C is

<600µA (±2%), while the standard deviation of the I

distribution is <0.1mA (0.8%) at 25 C. Tighter I

CC  
translates to more consistent AC parameters ensuring that  
units from each lot perform the same way, and easing the task  
of designing systems for wide temperature ranges. Critical AC  
parameters, Slew Rate and Bandwidth, each vary by less than  
±5% over the industrial temperature range (see Typical  
Performance Curves)
