67.10.4.3 Example of LSB Computation

The LSB is relative to the analog scale V_ADVREF.

The term LSB expresses the quantization step in volts, also used for one ADC code variation.

• Single-ended (SE) (ex: V_ADVREF = 3.0V)
  • Gain = 1, LSB = (3.0V / 4096) = 732 μV
• Differential (DIFF) (ex: V_ADVREF = 3.0V)
  • Gain = 0.5, LSB = (6.0V / 4096) = 1465 μV
