GENERAL DESCRIPTION
The AD8065/AD80661 Fast FET™ 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 and allow exceptionally low noise operation (7.0 n V/√Hz and 0.6 f A/√Hz) as well as very high input impedance.
With a wide supply voltage range from 5 V to 24 V, the ability to operate on single supplies, and a bandwidth of 145 MHz, the AD8065/AD8066 are designed to work in a variety of applications. For added versatility, the amplifiers also contain rail-to-rail outputs.
Despite the low cost, the amplifiers provide excellent overall performance. The differential gain and phase errors of 0.02% and 0.02°, respectively, along with 0.1 d B flatness out to 7 MHz, make these amplifiers ideal for video applications. Additionally, they offer a high slew rate of 180 V/µs, excellent distortion (SFDR of
- 88 d Bc @ 1 MHz), extremely high mon-mode rejection of
- 100 d B, and a low input offset voltage of 1.5 m V maximum under warmed up conditions. The AD8065/AD8066 operate using only a 6.4 m A/amplifier typical supply current and are capable of delivering up to 30 m A of load current.
