Operating Modes
The device has several operating modes dependent on
the applied voltages to the S1 and S0 pins as shown in
Table 1. In all the modes listed the channel multiplexers, D/A
Register, LFO, and the output pulse dividers will always be
powered up as long as there is a voltage source connected to
the V
DD
pin.
When only the S0 pin is at a logic one the pressure
measuring circuit in the device is powered up and the
pressure output signal is connected to the sample capacitor
through a multiplexer. When the S0 pin returns to the low
state the multiplexer will first turn off to store the signal on the
sample capacitor before powering down the measuring
circuitry.
When only the S1 pin is at a logic one the temperature
measuring circuit in the device is powered up and the
temperature output signal is connected to the sample
capacitor through a multiplexer. When the S1 pin returns to
the low state the multiplexer will first turn off to store the signal
on the sample capacitor before powering down the
measuring circuitry.
NOTE: All of the EEPROM trim bits will be powered up
regardless of whether the pressure or temperature
measuring circuitry is activated.
NOTE: If the voltage on the S1 pin exceeds 2.5 times the
voltage on the V
DD
pin the device will be placed into its Trim/
Test Mode.
NOTE: If the V
DD
supply source is switched off in order to
reduce current consumption, it is important that all input pins
be driven LOW to avoid powering up the device.
If any input pin (S1, S0, DATA, or CLK) is driven HIGH
while the V
DD
supply is switched off, the device may be
powered up through an ESD protection diode. In such a case,
the effective V
DD
voltage will be about 0.3 V less than the
voltage applied to the input pin, and the full device I
DD
current
will be drawn from the device driving input.
