ADI AD8066ARZ

电压反馈满摆幅

Overview

The AD8065/AD80661 FastFET amplifiers are voltage feedback amplifiers with FET inputs offering high performance and ease of use. The AD8065 is a single amplifier, and the AD8066ARZ is a dual amplifier. These amplifiers are developed in the Analog Devices, Inc. proprietary XFCB process and allow exceptionally low noise operation (7.0 nV/√Hz and 0.6 fA/√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/AD8066ARZ 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 dB 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 dBc @ 1 MHz), extremely high common-mode rejection of −100 dB, and a low input offset voltage of 1.5 mV maximum under warmed up conditions. The AD8065/ AD8066 operate using only a 6.4 mA/amplifier typical supply current and are capable of delivering up to 30 mA of load current. The AD8065/AD8066ARZ are high performance, high speed, FET input amplifiers available in small packages: SOIC-8, MSOP-8, and SOT-23-5. They are rated to work over the industrial temperature range of −40°C to +85°C.  FEATURES FET input amplifier 1 pA input bias current Low cost High speed: 145 MHz, −3 dB bandwidth (G = +1) 180 V/μs slew rate (G = +2) Low noise   7 nV/√Hz (f = 10 kHz)   0.6 fA/√Hz (f = 10 kHz) Wide supply voltage range: 5 V to 24 V Single-supply and rail-to-rail output Low offset voltage 1.5 mV maximum High common-mode rejection ratio: −100 dB Excellent distortion specifications SFDR −88 dBc @ 1 MHz Low power: 6.4 mA/amplifier typical supply current No phase reversal Small packaging: SOIC-8, SOT-23-5, and MSOP-8
