Accumulator values
Equation 5 describes the accumulator value in unipolar configuration. The voltage Vin is applied between the integrator input
and VDDM. The internal generated reference voltage is not connected. The accumulator value is a function of VDDM, the number
of samples (Nsample) taken and the SSD constant (SSDconst). The SSD constant and offset (SSDconst, SSDoffset) vary with
temperature and process.
Eqn. 5
Equation 6 describes the accumulator value in bipolar configuration. The voltage Vin is applied between the integrator input and
the reference output. The accumulator value depends on the same parameters as in the unipolar case but the inaccuracy of the
voltage reference (Vvref) is compensated.
