The HFA1106 is a high speed, low power current feedback
operational amplifier built with Intersil’s proprietary comple-
mentary bipolar UHF-1 process. This amplifier features a
compensation pin connected to the internal high impedance
node, which allows for implementation of external clamping
or bandwidth limiting.
Bandwidth limiting is accomplished by connecting a capaci-
tor (C_COMP) and series damping resistor (R_COMP) from pin
8 to ground. Amplifier performance for various values of
C_COMP is documented in the Electrical Specifications.
The HFA1106 is ideal for noise critical wideband applica-
tions. Not only can the bandwidth be limited to minimize
broadband noise, the HFA1106 is optimized for lower feed-
back resistors (R_F = 100Ω for A_V = +2) than most current
feedback amplifiers. The low feedback resistor reduces the
inverting input noise current contribution to total output
noise, while reducing DC errors as well. Please see the
“Application Information” section for details.
