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

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.
