DS1805E-010+ datasheet by Maxim Integrated Products

DS1805E-010+ Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the DS1805E-010+?
  The recommended operating voltage range for the DS1805E-010+ is 2.7V to 5.5V, although it can operate down to 2.2V with reduced performance.
• How do I ensure reliable operation of the DS1805E-010+ in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power consumption and ensure good thermal management, such as using a heat sink or providing adequate airflow.
• What is the maximum current rating for the DS1805E-010+?
  The maximum current rating for the DS1805E-010+ is 10mA per channel, although it is recommended to limit the current to 5mA per channel for reliable operation.
• How do I program the DS1805E-010+ to achieve the desired resistance values?
  The DS1805E-010+ can be programmed using a 3-wire serial interface, where the user sends a 16-bit command word to set the desired resistance value. The device also has a built-in EEPROM that allows the user to store the desired resistance values for recall during power-up.
• What is the typical response time of the DS1805E-010+ to a resistance change command?
  The typical response time of the DS1805E-010+ to a resistance change command is around 10μs, although this can vary depending on the specific application and operating conditions.
