1 MS4525HRD (High Resolution Digital) Integrated Digital Pressure Sensor (24-bit Σ ADC) Fast Conversion Down to 1 ms Low Power, 1 µa (standby < 0.15 µa) Supply Voltage: 1.8 to 3.6V Pressure Range: 1 to 150 PSI I 2 C and SPI Interface up to 20 MHz No External Components (Internal Oscillator) DESCRIPTION The MS4525HRD is a new generation of high resolution digital pressure sensors from MEAS with SPI and I 2 C bus interface. The sensor module includes a high linearity pressure sensor and an ultra low power 24-bit Σ ADC with internal factory calibrated coefficients. It provides a precise digital 24-bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high resolution temperature output allows the implementation of a thermometer function without any additional sensor. The MS4525HRD can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming internal registers in the device. This new sensor module generation is based on leading MEMS technology and latest benefits from MEAS proven experience and know-how in high volume manufacturing of pressure modules, which have been widely used for over a decade. The sensing principle employed leads to very low hysteresis and high stability of both pressure and temperature signal FEATURES APPLICATIONS PSI Pressure Ranges Factory Automation PCB Mountable Altitude and Airspeed Measurements Digital Output Medical Instruments Barbed Pressure Ports Leak Detection STANDARD RANGES (PSI) Pressure Absolute Gauge Differential 1 DS, SS, TP, MM, DS, SS,TP, MM 2 DS, SS, TP, MM, DS, SS,TP, MM 5 DS, SS, TP, MM, DS, SS,TP,MM 15 SS, TP,MM DS, SS, TP, MM, DS, MM 30 SS, TP,MM DS, SS, TP, MM, DS, MM 50 SS, TP,MM DS, SS, TP, MM, DS, MM 100 SS, TP,MM DS, SS, TP, MM, DS, MM 150 SS, TP,MM DS, SS, TP, MM, DS, MM See Package Configurations: DS= Dual Side Port, SS= Single Side Port, TP= Top Port, MM= Dual Manifold Mount, MS4525HRD October /22
