CY8CLEDAC01 Frequently Asked Questions (FAQs)

• What is the maximum current that the CY8CLEDAC01 can source or sink?
  The CY8CLEDAC01 can source up to 10mA and sink up to 20mA per pin, making it suitable for driving LEDs directly.
• How do I configure the CY8CLEDAC01 for 8-bit or 16-bit mode?
  The CY8CLEDAC01 can be configured for 8-bit or 16-bit mode by setting the MODE pin high or low, respectively, during power-up. The default mode is 8-bit.
• What is the purpose of the VREF pin on the CY8CLEDAC01?
  The VREF pin is used to set the reference voltage for the internal DAC. It can be connected to an external voltage source or left unconnected to use the internal 1.024V reference voltage.
• Can I use the CY8CLEDAC01 as a general-purpose I/O expander?
  Yes, the CY8CLEDAC01 can be used as a general-purpose I/O expander, but it is optimized for LED driving applications and may not be the most suitable choice for other uses due to its limited current sourcing and sinking capabilities.
• How do I update the LED brightness using the CY8CLEDAC01?
  The LED brightness can be updated by writing a new value to the DAC register using the I2C interface. The CY8CLEDAC01 supports 256 levels of brightness control.
