Design Considerations
Segment resistors are desirable to minimize power dissipation and chip heating The DS75492 serves as a good digit driver when it is desired to drive bright displays When using this driver with a 5V supply at room temperature the display can be driven without segment resistors to full illumination The user must use caution in this mode however to prevent overheating of the dev... |
