The HFA1412/883 is a quad closed loop Buffer featuring
user programmable gain and high speed performance. Man-
ufactured on Intersilâs proprietary complementary bipolar
UHF-1 process, this device offers wide -3dB bandwidth of
340MHz, very fast slew rate, excellent gain ï¬atness and high
output current.
A unique feature of the pinout allows the user to select a volt-
age gain of +1, -1, or +2, without the use of any external
components. Gain selection is accomplished via connec-
tions to the inputs, as described in the âApplication Informa-
tionâ section. The result is a more ï¬exible product, fewer part
types in inventory, and more efï¬cient use of board space.
Compatibility with existing op amp pinouts provides ï¬exibility
to upgrade low gain ampliï¬ers, 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.
Applications
⢠Flash A/D Driver
⢠Video Switching and Routing
⢠Pulse and Video Ampliï¬ers
⢠Wideband Ampliï¬ers
⢠RF/IF Signal Processing
⢠Medical Imaging Systems
