I²C Precision Altimeter
The MPL3115A2 employs a MEMS pressure sensor with an I²C interface to
provide accurate Pressure/Altitude and Temperature data. The sensor outputs
are digitized by a high resolution 24-bit ADC. Internal processing removes
compensation tasks from the host MCU system. Multiple user-programmable,
power saving, interrupt and autonomous data acquisition modes are available,
including programmed acquisition cycle timing, and poll-only modes. Typical
active supply current is 40 A per measurement-second for a stable 30 cm
output resolution. Pressure output can be resolved with output in fractions of a
Pascal, and Altitude can be resolved in fractions of a meter.
The MPL3115A2 is offered in a 5 mm by 3 mm by 1.1 mm LGA package and
specified for operation from -40C to 85C. Package is surface mount with a
stainless steel lid and is RoHS compliant.
