Description

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.

The ISL59112 is designed to meet the needs very low power and bandwidth criteria inherent to battery operated communication, instrumentation, and modern industrial applications such as video on demand, cable set-top boxes, DVD players, and HDTV. The ISL59112 is offered in a space-saving SC-70 package guaranteed to a 1mm maximum height constraint and specified for operation from -40°C to +85°C temperature range.
