C Precision
Altimeter
The Xtrinsic MPL3115A2 employs a MEMS pressure sensor with an I
2
C
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 μA per measurement-second for a
stable 10 cm output resolution.
The MPL3115A2 is offered in a 5 mm x 3 mm x 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.
