Either can be used for analog or digital video signals and for high-speed data transmission. The AD8129 and AD8130 are differential- to-single-ended amplifiers with extremely high CMRR at high frequency. Therefore, they can also be effectively used as high-speed instrumentation amps or for converting differential signals to single-ended signals. The AD8129 is a low-noise high-gain (10 or greater) version intended for applications over very long cables where signal attenuation is significant. The AD8130 is stable at a gain of one and can be used for those applications where lower gains are required. Both have user adjustable gain to help compensate for losses in the transmission line. The gain is set by the ratio of two resistor values. The AD8129 and AD8130 have very high input impedance on both inputs regardless of the gain setting. The AD8129 and AD8130 have excellent common-mode rejec- tion (70 dB @ 10 MHz) allowing the use of low cost unshielded twisted-pair cables without fear of corruption by external noise sources or crosstalk. The AD8129 and AD8130 have a wide power supply range from single 5 V supply to ±12 V, allowing wide common-mode and differential-mode voltage ranges while maintaining signal integrity. The wide common-mode voltage range will enable the driver receiver pair to operate without isolation transform- ers in many systems where the ground potential difference between drive and receive locations is many volts. The AD8129 and AD8130 have considerable cost and performance improve- ments over op amps and other multi-amplifier receiving solutions. 120 110 100 90 80 70 60 50 40 30 10k 100k 1M 10M 100M FREQUENCY – Hz Figure 1.
