40MHz Rail-to-Rail Video Buffer

The ISL59112 is a single rail-to-rail 6dB video buffer with a 3dB roll-off frequency of 40MHz and a slew rate of 60V/µs. Input signal DC restoration is accomplished with an internal sync tip clamp. Operating from single supplies ranging from +2.5V to +3.6V and sinking an ultra-low 2mA quiescent current, the ISL59112 is ideally suited for low power, battery-operated applications. It also features inputs capable of reaching down to 0.15V below the negative rail. Additionally, an enable high pin shuts the part down in under 20ns.
