MPL3150A2 Datasheet | NXP Semiconductors

description The MPL3150A2 is a pact, piezoresistive, absolute pressure sensor with an I2C digital interface. MPL3150A2 has a wide operating range of 50 k Pa to 150 k Pa. The MEMS is temperature pensated utilizing an on-chip temperature sensor. The pressure and temperature data is fed into a high-resolution ADC to provide fully pensated and digitized outputs for pressure in Pascals and temperature in °C. The internal processing in MPL3150A2 removes pensation and unit conversion load from the system MCU, simplifying system design. MPL3150A2's advanced ASIC has multiple user programmable modes such as power saving, interrupt and autonomous data acquisition modes, including programmed acquisition cycle timing, and poll-only modes. Typical active supply current is 40 μA per measurement-second and is offered in a 5 mm x 3 mm x 1.1 mm LGA Ro HS pliant package. 2 Features and benefits - Operating range: 50 k Pa to 150 k Pa absolute pressure - Calibrated range: 70 k Pa to 150 k Pa absolute pressure - Calibrated temperature output: - 40 °C to 85 °C - I2C digital output interface - Fully pensated internally - Direct reading - Pressure: 20-bit measurement (Pascals) - 50 k Pa to 150 k Pa - Temperature: 12-bit measurement (°C) - - 40 °C to 85 °C - Programmable interrupts - Autonomous data acquisition - Embedded 32-sample FIFO - Data logging up to 12 days using the FIFO - One-second to nine-hour data acquisition rate - 1.95 V to 3.6 V supply voltage, internally regulated - 1.6 V to 3.6 V digital interface supply voltage - Operating temperature from - 40 °C to +85 °C NXP Semiconductors I2C precision pressure sensor 3 Applications - High-accuracy barometry - Smartphones, tablets, and wearable devices - GPS applications: dead reckoning, map assist, navigation, enhancement for emergency services - Weather station equipment 4 Ordering information Table 1. Ordering information Device number Shipping Package Number of ports Pressure Type None Single Dual Gauge Differential...
