FUNCTION DESCRIPTION
In LED display application, SD16730 can maintain the current nearly no variations among different channels or
chips. The maximum current variation range is ±3% between channels and ±6% between chips.
This device has only one ground pin shared by signal, output sink current, and power ground. It is advisable to
pattern the ground layout with minimized inductance so that the switching noise induced by the input signals and
the output sink current would not cause chip malfunction. To prevent drivers’ outputs from damaging by
