HFA1112 В® Data Sheet FN2992.8 July 27, 2005 850MHz, Low Distortion Programmable
Gain Buffer Amplifiers
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, these devices offer a wide -3dB
bandwidth of 850MHz, very fast slew rate, excellent gain
flatness, low distortion and high output current. Features User Programmable for Closed-Loop Gains of +1, -1 or +2
without Use of External Resistors Wide -3dB Bandwidth 850MHz Very Fast Slew Rate 2400V/Вµs Fast Settling Time (0.1%) . 11ns High Output Current . 60mA 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. Excellent Gain Accuracy . 0.99V/V 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. RF/IF Processors This amplifier is available with programmable output limiting
as the HFA1113. For applications requiring a standard buffer
pinout, please refer to the HFA1110 data sheet. Line Driving HFA1112 (PDIP, SOIC)
