AD812

双通道，电流反馈型低功耗运算放大器 Dual, Current Feedback Low Power Op Amp

PRODUCT DESCRIPTION

The is a low power, single supply, dual video amplifier. Each of the amplifiers have 50 mA of output current and are optimized for driving one back-terminated video load 150 Ω each. Each amplifier is a current feedback amplifier and features gain flatness of 0.1 dB to 40 MHz while offering differential gain and phase error of 0.02% and 0.02°. This makes the AD812 ideal for professional video electronics such as cameras and video switchers.
