... MHz, reducing radiated EMI and suppressing harmonics. Manufactured on ADI’s next generation XFCB bipolar process, the AD8131 has a –3 dB bandwidth of 400 MHz and delivers a differential signal with very low harmonic distortion. The AD8131 is a differential driver for the transmission of high-speed signals over low-cost twisted pair or coax cables ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8131 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... The AD8131 differs from conventional op amps in that it has two outputs whose voltages move in opposite directions. Like an op amp, it relies on high open-loop gain and negative feed- back to force these outputs to the desired voltages. The AD8131 behaves much like a standard voltage feedback op amp and makes it easy to perform single-ended-to-differential conversion, common-mode level-shifting, and amplifi ...

... The two resistors in series with each output terminate the line at the transmit end. Since the impedances of the outputs of the AD8131 are very low, they can be thought short circuit, and the two terminating resistors form a 100 Ω termination at the transmit end of the transmission line. The receive end is directly terminated by a 100 Ω ...
