TFT-LCD backplane (V
divider string. They feature rail-to-rail input and output
capability, they are unity gain stable, and have low power
consumption (typical 600µA per amplifier). The ISL78020
and ISL78022 have a -3dB bandwidth of 12MHz while
maintaining a 10V/µs slew rate.

Short Circuit Current Limit
The ISL78020 and ISL78022 will limit the short circuit
current to ±180mA if the output is directly shorted to the
positive or the negative supply. If an output is shorted for a
long time, the junction temperature will trigger the
Over-Temperature Protection limit and hence the part will
shut down.
