The HFA1130/883 is a high speed, wideband current feed-
back amplifier featuring programmable output clamps. Built
with Intersil’ proprietary complementary bipolar UHF-1 pro-
cess, it is the fastest monolithic amplifier available from any
semiconductor manufacturer.
This amplifier is the ideal choice for high frequency applica-
tions requiring output limiting, especially those needing ultra
fast overdrive recovery times. The output clamp function
allows the designer to set the maximum positive and nega-
tive output levels, thereby protecting later stages from dam-
age or input saturation. The sub-nanosecond overdrive
recovery time quickly returns the amplifier to linear operation
following an overdrive condition.
The HFA1130/883’s wide bandwidth, fast settling character-
istic, and low output impedance, coupled with the output
clamping ability, make this amplifier ideal for driving fast A/D
converters.
Component and composite video systems will also benefit
from this amplifier’s performance, as indicated by the excel-
lent gain flatness, and 0.03%/0.05 Degree Differential Gain/
Phase specifications (R_L = 75Ω).
