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