DAC Resolution

Formulas

Step Size = V_ref / 2^N

V_out = Code x V_ref / 2^N

V_max = (2^N - 1) x V_ref / 2^N

The DAC converts a digital number into an analog voltage. Each increment of the digital code changes the output by one LSB.

Ejemplo Resuelto

10-bit DAC with 5 V reference, digital code = 512.

  1. Step size = 5 / 1024 = 4.883 mV
  2. V_out = 512 x 5 / 1024 = 2.500 V
  3. V_max = 1023 x 5 / 1024 = 4.995 V
