AD8131ARMZ Datasheet

Differential Amplifiers


The AD8131ARMZ is a differential or single-ended input to differential output driver requiring no external components for a fixed gain of 2. The AD8131ARMZ 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 AD8131ARMZ has a −3 dB bandwidth of 400 MHz and delivers a differential signal with very low harmonic distortion. AD8131ARMZ 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 AD8131ARMZ Applications • Video line driver• Digital line driver• Low power differential ADC driver• Differential in/out level shifting• Single-ended input to differential output driver
