Programable Swing Control

S3053

An external resistor can be connected across adjacent pins, VSWx to VEEx, where x is B0, B1, C0 and C1. 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. See Figure 7.

The 700 Ohm value is only used as an example. The power concious user could use as small a resistor value as

the application can handle.
