DS1804-100+ Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the DS1804-100+?
  The recommended operating voltage range for the DS1804-100+ is 2.7V to 5.5V.
• How do I ensure the DS1804-100+ is properly powered down to minimize power consumption?
  To properly power down the DS1804-100+, ensure that the SHDN pin is pulled high and the VCC pin is connected to a voltage source. This will put the device in shutdown mode, minimizing power consumption.
• What is the maximum current rating for the DS1804-100+?
  The maximum current rating for the DS1804-100+ is 10mA per channel.
• How do I configure the DS1804-100+ for 4-wire or 3-wire SPI operation?
  To configure the DS1804-100+ for 4-wire SPI operation, connect the SCK, MOSI, MISO, and SS pins accordingly. For 3-wire SPI operation, connect the SCK, MOSI, and MISO pins, and tie the SS pin high.
• What is the purpose of the WP pin on the DS1804-100+?
  The WP (Write Protect) pin is used to prevent accidental changes to the device's configuration. When the WP pin is pulled high, the device is in write-protect mode, and any attempts to write to the device will be ignored.
