The AD8065/AD8066 are high performance, high speed, FET GENERAL DESCRIPTION input amplifiers available in small packages: SOIC-8, MSOP-8, 1 The AD8065/AD8066 FastFET amplifiers are voltage feedback and SOT-23-5. They are rated to work over the industrial amplifiers with FET inputs offering high performance and ease temperature range of 40C to +85C. of use. The AD8065 is a single amplifier, and the AD8066 is a The AD8065WARTZ-R7 is fully qualified for automotive dual amplifier. These amplifiers are developed in the Analog applications. It is rated to operate over the extended temperature Devices, Inc. proprietary XFCB process and allow exceptionally range (40C to +105C), up to a maximum supply voltage low noise operation (7.0 nV/Hz and 0.6 fA/Hz) as well as very high input impedance. range of 5 V only. 24 With a wide supply voltage range from 5 V to 24 V, the ability to 21 G = +10 operate on single supplies, and a bandwidth of 145 MHz, the V = 200mV p-p O AD8065/AD8066 are designed to work in a variety of applications. 18 For added versatility, the amplifiers also contain rail-to-rail outputs. 15 G = +5 Despite the low cost, the amplifiers provide excellent overall 12 performance. The differential gain and phase errors of 0.02% 9 G = +2 and 0.02, respectively, along with 0.1 dB flatness out to 7 MHz, 6 make these amplifiers ideal for video applications. Additionally, 3 they offer a high slew rate of 180 V/s, excellent distortion (SFDR G = +1 0 of 88 dBc 1 MHz), extremely high common-mode rejection 3 of 100 dB, and a low input offset voltage of 1.5 mV maximum under warmed up conditions. The AD8065/AD8066 operate 6 0.1 1 10 100 1000 using only a 6.4 mA/amplifier typical supply current and are FREQUENCY (MHz) capable of delivering up to 30 mA of load current. Figure 2.
