The AD8132 is capable of driving either a Category 3 or Category 5 twisted pair or coaxial cable with minimal line Low power differential ADC drivers attenuation. The AD8132 has considerable cost and performance Differential gain and differential filtering improvements over discrete line driver solutions. Video line drivers Differential in/out level shifting Differential signal processing reduces the effects of ground noise Single-ended input to differential output drivers that plagues ground-referenced systems. The AD8132 can be used Active transformers for differential signal processing (gain and filtering) throughout a Automotive driver assistance signal chain, easily simplifying the conversion between differential Automotive infotainment and single-ended components. GENERAL DESCRIPTION The AD8132W is the automotive grade version, qualified for 125°C operation per the AEC-Q100. See the Automotive The AD8132 is a low cost differential or single-ended input to Products section for more details. differential output amplifier with resistor set gain. The AD8132 is a major advancement over op amps for driving differential input The AD8132 is available in both 8-lead SOIC and 8-lead MSOP ADCs or for driving signals over long lines. The AD8132 has a packages for operation over the extended industrial temperature unique internal feedback feature that provides output gain and range of −40°C to +125°C. phase matching balanced to −68 dB at 10 MHz, suppressing 6 harmonics and reducing radiated EMI. VS = ±5VG = +13VO, dm = 2V p-p Manufactured using the next-generation of Analog Devices, Inc., RL, dm = 499Ω XFCB bipolar process, the AD8132 has a −3 dB bandwidth of 0 350 MHz and delivers a differential signal with −99
