LTC1609CG#PBF datasheet by Linear Technology

LTC1609CG#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC1609CG?
  The maximum input voltage that can be applied to the LTC1609CG is 5.5V, exceeding which may cause damage to the device.
• How do I ensure the LTC1609CG is in a low-power state?
  To ensure the LTC1609CG is in a low-power state, the SHDN pin should be pulled low. This will reduce the quiescent current to less than 10μA.
• What is the recommended layout and routing for the LTC1609CG?
  For optimal performance, it is recommended to follow a star-ground layout, with the analog and digital grounds separated and connected at a single point. Additionally, keep the input and output traces short and away from noise sources.
• How do I filter out noise and ripple on the output of the LTC1609CG?
  To filter out noise and ripple, a low-pass filter can be added to the output of the LTC1609CG. A capacitor in the range of 1-10μF can be used in conjunction with a series resistor to filter out high-frequency noise.
• What is the thermal resistance of the LTC1609CG package?
  The thermal resistance of the LTC1609CG package is 45°C/W (junction-to-ambient) and 10°C/W (junction-to-case).
