1 General description
The MPL115A2 is an absolute pressure sensor with a digital I2C output targeting low
cost applications. A miniature 5 x 3 x 1.2 mm LGA package is ideally suited for the space
constrained requirements of portable electronic devices. Low current consumptions of
5 μA during Active mode and 1 μA during Shutdown (Sleep) mode are essential when
focusing on low-power applications. The wide operating temperature range spans from –
40 °C to +105 °C to fit demanding environmental conditions.
The MPL115A2 employs a MEMS pressure sensor with a conditioning IC to provide
accurate pressure measurements from 50 to 115 kPa. An integrated ADC converts
pressure and temperature sensor readings to digitized outputs via a I2C port. Factory
calibration data is stored internally in an on-board ROM. Utilizing the raw sensor output
and calibration data, the host microcontroller executes a compensation algorithm to
render Compensated Absolute Pressure with ±1 kPa accuracy.
The MPL115A2 pressure sensor’s small form factor, low power capability, precision, and
digital output optimize it for barometric measurement applications.

Function
Power Supply Connection: VDD range is 2.375 V to 5.5 V.
1 μF connected to ground.
Ground
Shutdown: Connect to GND to disable the device. When in
shutdown, the part draws no more than 1 μA supply current and
all communications pins (RST, SCL, SDA) are high impedance.
Connect to VDD for normal operation.
Reset: Connect to ground to disable I2C communications.
No connection
Serial data I/O line
Serial clock input.
[1] Use 4.7 kΩ pullup resistors for I2C communication.
7 Handling and Board Mount Recommendations
The sensor die is sensitive to light exposure. Direct light exposure through the port hole
can lead to varied accuracy of pressure measurement. Avoid such exposure to the port
during normal operation.
7.1 Methods of Handling
Components can be picked from the carrier tape using either the vacuum assist or the
mechanical type pickup heads. A vacuum assist nozzle type is most common due to its
lower cost of maintenance and ease of operation. The recommended vacuum nozzle
configuration should be designed to make contact with the device directly on the metal
cover and avoid vacuum port location directly over the vent hole in the metal cover of the
