Features
Description
• This Circuit is Processed in Accordance to MIL-STD- The HA-2842/883 is a wideband, high slew rate, operational
883 and is Fully Conformant Under the Provisions of amplifier featuring an outstanding combination of speed,

bandwidth, and output drive capability. This amplifier’s per-
formance is further enhanced through stable operation down
to closed loop gains of +2, the inclusion of offset null con-
trols, and by its excellent video performance.
• Low AC Variability Over Process and Temperature
• Stable at Gains of 2 or Greater
The capabilities of the HA-2842/883 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 sig-
nal conditioning circuits and video amplifiers. Gain flatness
of 0.035dB, combined with differential gain and phase speci-
fications of 0.02%, and 0.03 degrees, respectively, make the
HA-2842/883 ideal for component and composite video
applications.

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 variabil-
ity. For example, the average ICC variation from +85oC to
-40oC is <600µA (±2%),while the standard deviation of the

CC distribution is <0.1mA (0.8%) at +25oC. Tighter ICC con-
trol 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.
