The AD8131 is a major advancement over op amps for driving signals over long lines or for driving differential input ADCs. The AD8131 has a unique internal feedback feature that provides output gain and phase matching that are balanced to –60 dB at 10 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. The AD8131 can be used for either analog or digital video signals or for other high-speed data transmission. The AD8131 driver is capable of driving either Cat3 or Cat5 twisted pair or coax with minimal line attenuation. The AD8131 has considerable cost and performance improvements over discrete line driver solutions. The AD8131 can replace transformers in a variety of applica- tions preserving low frequency and dc information. The AD8131 does not have the susceptibility to magnetic interference and hysteresis of transformers, while being smaller in size, easier to work with, and has the high reliability associated with ICs. The AD8131’s differential output also helps balance the input for differential ADCs, optimizing the distortion performance of the ADCs. The common-mode level of the differential output is adjustable by a voltage on the VOCM pin, easily level-shifting the input signals for driving single supply ADCs with dual supply signals. Fast overload recovery preserves sampling accuracy. The AD8131 will be available in both SOIC and µSOIC packages for operation over –40 C to +85 C.
