An analog to digital (A/D) conversion can be accomplished
with eight (8) different threshold levels in a successive
approximation algorithm; or the OUT pin can be set to trip at
some alarm level. The voltage on the sample capacitor will
maintain long enough for a single 8-bit conversion, but may
need to be refreshed with a new measured reading if the read
interval is longer than the specified hold time, tSH.
The counter that determines the number of clock pulses
into the device is reset whenever the device is placed into the
Measure Pressure or Measure Temperature Modes. This
provides a means to reset the data transfer count in case the
clock stream is corrupted during a transmission. In these two
modes the DATA and CLK pins should not be clocked to
reduce noise in the captured pressure or temperature data.
Any change in the DAR contents should be done during the
Standby or Output Read Modes.
Both the serial bit counter and the state of the DAR are
undefined following power up of the device. The serial bit
counter can be reset by cycling either the SO pin or the S1/
VPP pin to a high level and then back low. The DAR can then
be reset to the lowest level by holding the DATA pin low while
bursting the CLK pin with eight (8) clock pulses.

Pressure Sensor Output
The pressure channel compares the output of its analog
measurement circuit to the D/A reference voltage. The device
is calibrated at two different nominal values depending on the
calibration option.
Temperature Sensor Output
The temperature channel compares the output of a
positive temperature coefficient (PTC) resistor driven by a
switched current source. The current source is only active
when the temperature channel is selected.
APPLICATIONS
Suggested application example is shown in Figure 6.
