BLOCK DIAGRAM Application Information The ISL59110 is a single supply rail-to-rail output amplifier achieving a -3dB bandwidth of around 8MHz and slew rate of about 40V/µs while demanding only 2mA of supply current. This part is ideally suited for applications with specific micropower consumption and high bandwidth demands. As the performance characteristics above and the features described below, the ISL59110 is designed to be very attractive for portable composite video applications. The ISL59110 features a sync clamp, low pass function, and SAG network at the output facilitating reduction of typically large AC coupling capacitors. See Figure 24. Internal Sync Clamp The typical embedded video DAC operates from a ground referenced single supply. This becomes an issue because the lower level of the sync pulse output may be at a 0V reference level to some positive level. The problem is presenting a 0V input to most single supply driven amplifiers will saturate the output stage of the amplifier resulting in a FIGURE 22.
