HFA1412
Quad, 350MHz, Low Power,
Programmable Gain Buffer Amplifier
The HFA1412 is a quad closed loop Buffer featuring user
programmable gain and high speed video performance.
A unique feature of the HFA1412’s pinout allows the user to
select a voltage gain of +1, -1, or +2 (see the “Application
Information” section). The on-chip gain setting resistors
eliminate eight external resistors, thus saving board space or
freeing up space for termination resistors. The on-chip
feedback resistor is preset at the optimum value, and also
eliminates worries about parasitic feedback capacitance.
Additionally, the capacitance sensitive summing node is
buried inside the package where it is unaffected by PCB
parasitics. Compatibility with existing op amp pinouts
provides flexibility to upgrade low gain amplifiers, while
decreasing component count. Unlike most buffers, the
standard pinout provides an upgrade path should a higher
closed loop gain be needed at a future date.
The HFA1412 is an excellent choice for component and
composite video systems as indicated by the excellent gain
flatness, and 0.03%/0.02 Degree Differential Gain/Phase
specifications (R
L
=
150
). Its ability to deliver a gain of +2
with no external resistors makes it particularly desirable for
applications driving double terminated cables.
For Military product, refer to the HFA1412/883 data sheet.

*Pb-free PDIPs can be used for through hole wave solder
processing only. They are not intended for use in Reflow solder
processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
