PRODUCT DESCRIPTION

The AD8170(2:1) and AD8174(4:1) are very high speed buffered multiplexers. These multiplexers offer an internal current feedback output amplifier whose gain can be programmed via external resistors and is capable of delivering 50 mA of output current. They offer –3 dB signal bandwidth of 250 MHz and slew rate of greater than 1000 V/μs. Additionally, the AD8170 and AD8174 have excellent video specifications with low differential gain and differential phase error of 0.02 and 0.05° and 0.1 dB flatness out to 80 MHz. With a low 78 dB of crosstalk and better than 88 dB isolation, these devices are useful in many high speed applications. These are low power devices consuming only 9.7 mA from a ±5 V supply.
