Programable Swing Control
An external resistor can be connected across adjacent pins, VSWx to VEEx, where x is A0, A1, B0 and B1. This
will result in a decreased Vswing for the specified output and a decrease in chip power dissipation. For example,
if a 700 Ohm resistor is used, the Vswing will decrease from its full scale swing of approximately 570mV to
250mV and that specific output will draw approximately 13mA less. All four outputs can be independently set. If
no external resistor is used, the output swing will default to its full scale value.
The 700 Ohm value is only used as an example. The power conscious user could use as small a resistor value
as the application can handle.
