LTC1290CCSW#PBF datasheet by Linear Technology

LTC1290CCSW#PBF Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the LTC1290 can handle?
  The LTC1290 can handle clock frequencies up to 1.5MHz.
• How do I ensure accurate conversions with the LTC1290?
  To ensure accurate conversions, make sure to follow proper PCB layout guidelines, use a low-noise power supply, and minimize digital noise coupling to the analog inputs.
• Can I use the LTC1290 with a single-ended analog input?
  Yes, the LTC1290 can be used with single-ended analog inputs, but it's recommended to use a differential input configuration for better common-mode rejection and noise immunity.
• What is the purpose of the SYNC pin on the LTC1290?
  The SYNC pin is used to synchronize the conversion process with an external clock or signal, allowing for simultaneous sampling of multiple channels.
• How do I handle overvoltage conditions on the analog inputs of the LTC1290?
  Use external voltage limiting resistors or clamping diodes to protect the analog inputs from overvoltage conditions, and consider adding input protection circuits for added safety.
