Figure 4. Measurement Sequence
Parameter Measurement
The DS2786B uses a sigma-delta A/D converter to
make measurements. The measurement sequence
shown in Figure 4 repeats continuously while the
DS2786B is in Active Mode. The VOUT pin is activated
tPRE before the AIN0 and AIN1 conversion to allow for
the VOUT output voltage to settle. The DS2786B can be
configured to measure temperature using its on-chip
sensor instead of the AIN1 input. When the internal tem-
perature measurement uses the AIN1 conversion time-
slot, VOUT is not activated. A full sequence of voltage
measurements nominally takes 1760ms to complete.
