HA-2841
FN2843.4
50MHz, Fast Settling, Unity Gain Stable,
Video Operational Amplifier
The HA-2841 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 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, combined with differential gain and phase
specifications of 0.03%, and 0.03 degrees, respectively,
make the HA-2841 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 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 characteristic curves).
