Analog Devices Inc. AD8066 FastFET™ Amplifiers

Analog Devices Inc. AD8066 FastFET™ Amplifiers are voltage feedback amplifiers with FET inputs offering high performance and ease of use. The AD8065 is a single amplifier, and the AD8066 is a dual amplifier. These amplifiers are developed in the Analog Devices, Inc. proprietary XFCB process. The AD8066 allows exceptionally low noise operation (7.0nV/√Hz and 0.6fA/√Hz) and very high input impedance.
