HFA1115
225MHz, Low Power, Output
Limiting, Closed Loop Buffer Amplifier
The HFA1115 is a high speed closed loop Buffer featuring both
user programmable gain and output limiting. Manufactured on
Intersil’sproprietarycomplementarybipolarUHF-1process,the
HFA1115 also offers a wide -3dB bandwidth of 225MHz, very
fast slew rate, excellent gain flatness and high output current.
This buffer is the ideal choice for high frequency applications
requiring output limiting, especially those needing ultra fast
overload recovery times. The limiting function allows the
designer to set the maximum positive and negative output
levels, thereby protecting later stages from damage or input
saturation. The HFA1115 also allows for voltage gains of +2,
+1, and -1, without the use of external resistors. Gain
selection is accomplished via connections to the inputs, as
described in the “Application Information” text. 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 HFA1115/883
data sheet.
