AD8131

FEATURES High speed 400 MHz, −3 dB full power bandwidth 2000 V/μs slew rate Fixed gain of 2 with no external components Internal common-mode feedback to improve gain and phase balance: −60 dB @ 10 MHz Separate input to set the common-mode output voltage Low distortion: 68 dB SFDR @ 5 MHz 200 Ω load Power supply range +2.7 V to ±5 V APPLICATIONS Video line driver Digital line driver Low power differential ADC driver Differential in/out level shifting Single-ended input to differential output driver GENERAL DESCRIPTION The AD8131 is a differential or single-ended input to differential output driver requiring no external components for a fixed gain of 2. 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 the Analog Devices, Inc. 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...
