High Output Drive feedback amplifier and features gain flatness of 0.1 d B to 100 MHz 70 m A Output Current while offering differential gain and phase error of 0.01% and Drives Up to Four Back-Terminated Loads (75 V Each) 0.025°. This makes the AD8001 ideal for professional video While Maintaining Good Differential Gain/Phase electronics such as cameras and video switchers. Additionally, Performance (0.05%/0.258) the AD8001’s low distortion and fast settling make it ideal for buffer high-speed A-to-D converters.

APPLICATIONS

The AD8001 offers low power of 5.5 m A max (VS = ±5 V) and

A-to-D Driver

can run on a single +12 V power supply, while being capable of

Video Line Driver

Professional Cameras delivering over 70 m A of load current. These features make this Video Switchers amplifier ideal for portable and battery-powered applications Special Effects where size and power are critical.

RF Receivers

The outstanding bandwidth of 800 MHz along with 1200 V/µs of slew rate make the AD8001 useful in many general purpose
