Description
The HFA1114 is a closed loop Buffer featuring user
programmable gain and ultra high speed performance.
Manufactured on Intersil’ proprietary complementary bipolar
UHF-1 process, the HFA1114 offers a wide -3dB bandwidth
of 850MHz, very fast slew rate, excellent gain flatness, low
distortion and high output current.
A unique feature of the pinout allows the user to select a
voltage gain of +1, -1, or +2, without the use of any external
components. Gain selection is accomplished via connections
to the inputs, as described in the “Application Information”
section. The result is a more flexible product, fewer part types
in inventory, and more efficient use of board space.
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.
For applications requiring a standard buffer pinout, please
refer to the HFA1110 datasheet.
