MAX6956AAX+ datasheet by Maxim Integrated Products

MAX6956AAX+ Frequently Asked Questions (FAQs)

• What is the maximum current that the MAX6956AAX+ can sink or source?
  The MAX6956AAX+ can sink up to 25mA per segment and source up to 10mA per segment.
• How do I ensure that the display is updated correctly when using the MAX6956AAX+?
  To ensure correct display updates, make sure to follow the recommended timing diagrams and pulse widths for the clock, data, and latch signals. Also, ensure that the display is properly initialized and that the correct display mode is selected.
• What is the purpose of the internal oscillator on the MAX6956AAX+?
  The internal oscillator on the MAX6956AAX+ is used to generate the clock signal for the display. It can be used in place of an external clock signal, but it is not as accurate and may not be suitable for all applications.
• Can the MAX6956AAX+ be used with multiple displays?
  Yes, the MAX6956AAX+ can be used with multiple displays, but it requires additional external circuitry to multiplex the display signals. The MAX6956AAX+ can only drive one display at a time, so the displays must be multiplexed to share the same driver.
• What is the recommended layout and routing for the MAX6956AAX+?
  To minimize noise and ensure reliable operation, it is recommended to follow good PCB layout and routing practices, such as keeping the clock and data lines short and away from noise sources, and using a solid ground plane to reduce electromagnetic interference.
