configurations. This prevents drawing down the supply voltage (VDD).
MODES OF OPERATION
This device has several operating modes whose primary purpose is power management and is controlled by the Mode
Register. This section describes these modes.
Continuous-Measurement Mode
During continuous-measurement mode, the device continuously makes measurements, at user selectable rate, and
places measured data in data output registers. Data can be re-read from the data output registers if necessary; however,
if the master does not ensure that the data register is accessed before the completion of the next measurement, the data
output registers are updated with the new measurement. To conserve current between measurements, the device is
placed in a state similar to idle mode, but the Mode Register is not changed to Idle Mode. That is, MD[n] bits are
unchanged.
Settings in the Configuration Register A affect the data output rate (bits DO[n]), the measurement
configuration (bits MS[n]), when in continuous-measurement mode.
All registers maintain values while in continuous-
2
measurement mode. The I
C bus is enabled for use by other devices on the network in while continuous-measurement
mode.
Single-Measurement Mode
This is the default power-up mode. During single-measurement mode, the device makes a single measurement and
places the measured data in data output registers. After the measurement is complete and output data registers are
updated, the device is placed in idle mode, and the Mode Register is changed to idle mode by setting MD[n] bits. Settings
in the configuration register affect the measurement configuration (bits MS[n])when in single-measurement mode.
All
2
registers maintain values while in single-measurement mode. The I
C bus is enabled for use by other devices on the
network while in single-measurement mode.
Idle Mode
2
During this mode the device is accessible through the I
C bus, but major sources of power consumption are disabled,
such as, but not limited to, the ADC, the amplifier, and the sensor bias current. All registers maintain values while in idle
2
mode. The I
C bus is enabled for use by other devices on the network while in idle mode.
