HFA1113/883
Output Limiting, Ultra High Speed
Programmable Gain, Buffer Amplifier
Description
The HFA1113/883 is a closed loop buffer featuring a high
degree of gain accuracy, wide bandwidth, low distortion, and
programmable output limiting. This buffer is the ideal choice
for high frequency applications requiring output limiting,
especially those needing ultra fast overdrive recovery times.
The output limiting function allows the designer to set the
maximum positive and negative output levels, thereby pro-
tecting later stages from damage or input saturation. The
sub-nanosecond overdrive recovery time quickly returns the
amplifier to linear operation following an overdrive condition.
Component and composite video systems will also benefit
from this buffer’s performance, as indicated by the excellent
gain flatness, and 0.02%/0.04 Deg. Differential Gain/Phase
specifications (R
L
= 150
).
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, as described in the “Design Information” sec-
tion. 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.
This amplifier is available without output limiting as the
HFA1112/883. For applications requiring a standard buffer
pinout, please refer to the HFA1110/883 datasheet.
