PRODUCT DESCRIPTION
The outstanding bandwidth of 140 MHz along with 1000 V/µs The AD8013 is a low power, single supply, triple video of slew rate make the AD8013 useful in many general purpose amplifier. Each of the three amplifiers has 30 mA of output high speed applications where a single +5 V or dual power current, and is optimized for driving one back terminated video supplies up to ± 6.5 V are required. Furthermore the AD8013’s load (150 Ω) each. Each amplifier is a current feedback amp- high speed disable function can be used to power down the lifier and features gain flatness of 0.1 dB to 60 MHz while offering amplifier or to put the output in a high impedance state. This can then be used in video multiplexing applications. The AD8013 is available in the industrial temperature range of
