This allows it to drive 65 dBc THD, f = 5 MHz C video loads with excellent differential gain and phase perfor- 33 dBm Third Order Intercept, F = 10 MHz 1 mance on only 50 mW of power. The AD8001 is a current 66 dB SFDR, f = 5 MHz feedback amplifier and features gain flatness of 0.1 dB to 100 MHz High Output Drive while offering differential gain and phase error of 0.01% and 70 mA Output Current 0.025. This makes the AD8001 ideal for professional video Drives Up to 4 Back-Terminated Loads (75 Each) electronics such as cameras and video switchers. Additionally, While Maintaining Good Differential Gain/Phase the AD8001s low distortion and fast settling make it ideal for Performance (0.05%/0.25 ) buffer high speed A-to-D converters. APPLICATIONS The AD8001 offers low power of 5.5 mA max (V = 5 V) and S A-to-D Drivers can run on a single +12 V power supply, while being capable of Video Line Drivers delivering over 70 mA of load current. These features make this Professional Cameras amplifier ideal for portable and battery-powered applications Video Switchers where size and power are critical. Special Effects RF Receivers The outstanding bandwidth of 800 MHz along with 1200 V/s of slew rate make the AD8001 useful in many general-purpose GENERAL DESCRIPTION high speed applications where dual power supplies of up to 6 V The AD8001 is a low power, high speed amplifier designed and single supplies from 6 V to 12 V are needed. The AD8001 is to operate on 5V supplies. The AD8001 features unique available in the industrial temperature range of 40C to +85C. 9 V = 5V S 6 R = 820 FB G = +2 3 R = 100 L 0 V = 5V S 3 R = 1k FB 6 9 12 10M 100M 1G FREQUENCY Hz Figure 1.
