MPL115A2 Datasheet | NXP Semiconductors

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 k Pa to 115 k Pa. An integrated ADC converts pressure and temperature sensor readings to digitized outputs via a I2C port. Factory calibration data is stored internally in an onboard ROM. Utilizing the raw sensor output and calibration data, the host microcontroller executes a pensation algorithm to render pensated Absolute Pressure with ±1 k Pa accuracy. The MPL115A2 pressure sensor’s small form factor, low-power capability, precision, and digital output optimize it for barometric measurement applications. 2 Features - Digitized pressure and temperature information together with programmed calibration coefficients for host micro use. - Factory calibrated - 50 k Pa to 115 k Pa absolute pressure - ±1 k Pa accuracy - 2.375 V to 5.5 V supply - Integrated ADC - I2C Interface (operates up to 400 k Hz) - 7-bit I2C address = 60h - Monotonic pressure and temperature data outputs - Surface mount Ro HS pliant package 3 Applications - Barometry (portable and desktop) - Altimeters - Weather stations - Hard-disk drives (HDD) - Industrial equipment - Health monitoring NXP Semiconductors Miniature I2C digital barometer, 50 k Pa to 115 k Pa - Air control systems 4 Ordering information Table 1. Ordering information Type number Package Name TSON8 Description LGA 8 I/O, 3 X 5 X 1.25 PITCH, SENSOR 1.2MAX MM PKG Version SOT1769-1 4.1 Ordering options Table...
