HA-2841/883
Wideband, Fast Settling, Unity Gain Stable,
Video Operational Amplifier
Description
The HA-2841/883 is a wideband, unity gain stable, operational
amplifier featuring a 50MHz unity gain bandwidth, and excellent
DC specifications. This amplifier’s performance is further
enhanced through stable operation down to closed loop gains of
+1, the inclusion of offset null controls, and by its excellent video
performance.
The capabilities of the HA-2841/883 are ideally suited for high
speed pulse and video amplifier circuits, where high slew rates
and wide bandwidth are required. Gain flatness of 0.05dB, com-
bined with differential gain and phase specifications of 0.03%,
and 0.03 degrees, respectively, make the HA-2841/883 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 variability. Tighter
I
CC
control translates to more consistent AC parameters ensur-
ing that units from each lot perform the same way, and easing the
task of designing systems for wide temperature ranges.
