GENERAL DESCRIPTION
The AD8065/AD8066 are high performance, high speed, FET The AD8065/AD80661 FastFET™ amplifiers are voltage feedback input amplifiers available in small packages: SOIC-8, MSOP-8, amplifiers with FET inputs offering high performance and ease and SOT-23-5. They are rated to work over the industrial of use. The AD8065 is a single amplifier, and the AD8066 is a temperature range of −40°C to +85°C. dual amplifier. These amplifiers are developed in the Analog The AD8065WARTZ-R7 is fully qualified for automotive Devices, Inc. proprietary XFCB process and allow exceptionally applications. It is rated to operate over the extended temperature low noise operation (7.0 nV/√Hz and 0.6 fA/
