Description

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-

8 to ground. Amplifier performance for various values of

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-

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.
