3. Functional description

The BMP388 consists of a Piezo-resistive pressure sensing element and a mixed-signal ASIC. The ASIC performs A/D

conversions and provides the conversion results and sensor specific compensation data through a digital interface.

BMP388 provides highest flexibility to the designer and can be adapted to the requirements regarding accuracy,

measurement time and power consumption by selecting from a high number of possible combinations of the sensor settings.

BMP388 can be operated in three power modes (see section 3.3):

sleep mode

normal mode

forced mode

In sleep mode, no measurements are performed. Normal mode comprises an automated perpetual cycling between an active

measurement period and an inactive standby period. In forced mode, a single measurement is performed. When the

measurement is finished, the sensor returns to sleep mode.
