The ADA4862-3 is a low cost, high speed, internally fixed, G = +2 op amp, ideal for RGB/HD/SD video applications.
The ADA4862-3 is a low‑cost, high‑speed triple operational amplifier with a fixed gain of G = +2, designed for consumer and professional video applications. It offers a 300 MHz –3 dB bandwidth, 750 V/µs slew rate, and low power consumption (5.3 mA per amplifier) while supporting supply voltages from 5 V to 12 V.
The document includes detailed specifications such as dynamic performance, distortion/noise data, absolute maximum ratings, thermal resistance, and an ordering guide for the 14‑lead SOIC package. A power‑down pin allows the device to enter a low‑power state of about 200 µA, simplifying board layout with on‑chip gain‑setting resistors.

The device draws about 14 mA per amplifier in its enabled state.
Yes, its operating supply range is 5 V to 12 V, so a 5 V single supply is supported.
Yes, the power‑down pin (= –Vs) reduces the supply current to about 200 µA when activated.
