HFA1112
850MHz, Low Distortion Programmable
Gain Buffer Amplifier
The HFA1112 is a closed loop Buffer featuring user
programmable gain and ultra high speed performance.
Manufactured on Intersil’s proprietary complementary
bipolar UHF-1 process, the HFA1112 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.
This amplifier is available with programmable output limiting
as the HFA1113. For applications requiring a standard buffer
pinout, please refer to the HFA1110 datasheet. For Military
product, refer to the HFA1112/883 data sheet.
