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
