Dual 350MHz, Low Power Closed Loop
Buffer Ampliï¬er
The HFA1212 is a dual closed loop Buffer featuring user
programmable gain and high speed performance.
Manufactured on Intersilâs proprietary complementary
bipolar UHF-1 process, these devices offer wide -3dB
bandwidth of 350MHz, very fast slew rate, excellent gain
ï¬atness 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 âApplication
Informationâ 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. For Military product, refer to the HFA1212/883
data sheet.
