HFA1212/883
Dual, High Speed, Low Power,
Video Closed Loop Buffer
Description
The HFA1212/883 is a dual closed loop Buffer featuring user
programmable gain and high speed performance. Manufac-
tured on Intersil’s proprietary complementary bipolar UHF-1
process, this device offers wide -3dB bandwidth of 340MHz,
very fast slew rate, excellent gain flatness 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 “Application Informa-
tion” 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.
