The AD8131 is a low-cost, high-speed differential driver. It features a high speed of 400 MHz, -3 dB full power bandwidth, 2000 V/μs slew rate, and a fixed gain of 2.
The AD8131 is a low‑cost, high‑speed differential driver designed for video, digital, and ADC line‑driver applications. It delivers a fixed gain of 2, internal common‑mode feedback for balanced output, and can drive twisted‑pair or coaxial cables with minimal attenuation.
The document lists detailed electrical specifications, absolute maximum ratings, pin functions, typical performance graphs, and ordering options for SOIC and MSOP packages, as well as application notes such as unity‑gain single‑ended‑to‑differential operation.
| Input Resistance (single‑ended) | 1.125 kΩ |
|---|---|
| Operating Temperature Range | –40 °C to +125 °C |
| Power Supply Range | +2.7 V to +5 V |
By leaving the –IN pin floating, the internal feedback creates a unity‑gain single‑ended‑to‑differential amplifier that requires no external components.
The AD8131 is available in both SOIC and MSOP surface‑mount packages.
The device operates from a supply voltage of +2.7 V up to +5 V.
