HFA1113
850MHz, Low Distortion, Output Limiting,
Programmable Gain, Buffer Amplifier
The HFA1113 is a high speed Buffer featuring user
programmable gain and output limiting coupled with ultra
high speed performance. This buffer is the ideal choice for
high frequency applications requiring output limiting,
especially those needing ultra fast overload recovery times.
The output limiting function allows the designer to set the
maximum positive and negative output levels, thereby
protecting later stages from damage or input saturation. The
sub-nanosecond overdrive recovery time quickly returns the
amplifier to linear operation following an overdrive condition.
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 “Application Information”
section. 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.
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 Degree Differential
Gain/Phase specifications (R
L
= 150).
For Military product, refer to the HFA1113/883 data sheet.
