AD8129 datasheet



The AD8129 / AD8130 are designed as receivers for the transmission of high speed signals over twisted-pair cables to work with the AD8131or AD8132drivers. Either can be used for analog or digital video signals and for high speed data transmission.

The AD8129/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 1 and can be used for 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/AD8130 have very high input impedance on both inputs, regardless of the gain setting.
