Q & A

  1. What is the resolution of the LTC2440IGN#TRPBF?
    The LTC2440IGN#TRPBF has a 24-bit resolution.
  2. What are the conversion speed/resolution combinations available?
    The LTC2440 offers ten different speed/resolution combinations ranging from 6.9Hz/200nV RMS to 3.5kHz/25µV RMS.
  3. What is the integral nonlinearity (INL) of the LTC2440IGN#TRPBF?
    The INL is 5ppm.
  4. How does the power dissipation vary with different conversion speeds?
    Power dissipation varies with the conversion speed and the duration of the sleep state. For example, it draws 240µA at 3.5kHz and 25µA at a 7Hz output rate.
  5. What type of digital interface does the LTC2440IGN#TRPBF use?
    The LTC2440IGN#TRPBF uses a flexible 3-wire or 4-wire digital interface.
  6. What is the operating temperature range of the LTC2440IGN#TRPBF?
    The operating temperature range is -40°C to 85°C.
  7. How does the LTC2440IGN#TRPBF manage power consumption?
    The LTC2440 automatically enters a low power sleep state after each conversion cycle, and power dissipation can be reduced by increasing the duration of this sleep state.
  8. What package type is the LTC2440IGN#TRPBF available in?
    The LTC2440IGN#TRPBF is available in a 16-lead SSOP (Narrow 0.15 Inch) package.
  9. Is the LTC2440IGN#TRPBF RoHS compliant?
    Yes, the LTC2440IGN#TRPBF is RoHS compliant.
  10. What are some typical applications for the LTC2440IGN#TRPBF?
    Typical applications include industrial automation, medical devices, and data acquisition systems.
