Applications Information

The LTC2484 is a low-power delta-sigma analog-to-digital converter with a simple 4-wire serial interface and automated differential input current cancellation. Let us investigate its operation and some of its practical applications.

The LTC2484 runs in three distinct states during the course of its operating cycle:

  • Conversion: The conversion phase kicks off the cycle. The LTC2484 acquires analog data and converts it to digital format during this stage.
  • Low-Power Sleep mode: Once the conversion is complete, the device enters a low-power sleep mode. Power consumption is greatly reduced here, resulting in energy conservation. As long as the chip select (CS) pin is maintained HIGH, the LTC2484 will remain in this condition. During this sleep state, the conversion result is stored in a static shift register.

When the CS pin is pulled LOW, the device leaves low-power mode and enters the data output state. If CS is set to HIGH before the first rising edge of the serial clock (SCK), the device enters low-power sleep mode, and the conversion result is stored in the internal static shift register. If CS remains LOW after the initial rising edge of SCK, however, the device begins to output the conversion result. Raise CS at this moment to end the data input and output states and start a fresh conversion. On the falling edge of SCK, the conversion result is moved out through the serial data output pin (SDO).

Wire Serial Interface

The LTC2484’s 4-wire serial interface simplifies communication and control. It consists of the following components:

  • Serial Data Output (SDO): This pin outputs the converted data in a serial format.
  • Serial Clock (SCK): SCK controls the timing of data transmission.
  • Chip Select (CS): CS is used to initiate and terminate operations, as well as control the sleep state.
  • Serial Data Input (SDI): SDI is where data is latched into the device, with the rising edge of SCK triggering this action.


In conclusion, the LTC2484IDD#TRPBF stands as a testament to modern analog-to-digital conversion technology, offering a remarkable blend of adaptability, precision, and advanced features.
