FN2766.7
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.

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

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)
