PRODUCT DESCRIPTION

The AD8074/AD8075 are high-speed triple video buffers with G = +1 and +2 respectively. They have a –3 dB full signal bandwidth in excess of 450 MHz, along with slew rates in excess of 1400 V/µs. With better than –80 dB of all hostile crosstalk and 90 dB isolation, they are useful in many high-speed applications. The differential gain and differential phase error are 0.01 and 0.01°. Gain flatness of 0.1 dB up to 50 MHz makes the AD8074/AD8075 ideal for RGB buffering or driving. They consume less than 30 mA on a ± 5 V supply.
