The MS4525DO is a small, ceramic based, PCB mounted pressure transducer from TE Connectivity.  The transducer is built using our proprietary UltraStable™ process and the latest CMOS sensor conditioning circuitry to create a low cost, high performance digital output pressure (14bit) and temperature (11bit) transducer designed to meet the strictest requirements from OEM customers. 

The MS4525DO is fully calibrated and temperature compensated with a total error band (TEB) of less than 1.0% over the compensated pressure range.  The sensor operates from single supply of either 3.3 or 5.0VDC and requires a single external component for proper operation 

The rugged ceramic transducer is available in side port, top port, and manifold mount and can measure absolute, gauge, differential, vacuum or compound pressure from 1 to 150psi. The 1/8” barbed pressure ports mate securely with 3/32” ID tubing.

## **Notes** 

1. Proper operation requires an external capacitor placed as shown in Connection Diagram.  Output is not ratiometric to supply voltage. 

2. The maximum deviation from a best fit straight line (BFSL) fitted to the output measured over the pressure range at 25C.  Includes all errors due to pressure non linearity, hysteresis, and non repeatability. 

3. Total pressure error band includes all accuracy errors, thermal errors over the compensated temperature range and span and offset calibration tolerances.  For ideal sensor output with respect to input pressure and temperature, reference Transfer Function charts below. TEB values are valid only at the calibrated supply voltage. 

4. The deviation from a best fit straight line (BFSL) fitted to the output measured over the compensated temperature range. 

5. For errors beyond the compensated temperature range, see Extended Temperature Multiplier chart below. 

6. Start time to data ready is the time to get valid data after POR (power on reset). The time to get subsequent valid data is then specified by the update time specification. 

7. This product can be configured for custom OEM requirements, contact factory for lower power consumption or higher accuracy.

## APPLICATION NOTES 

Measurement Specialties offers a comprehensive selection of product support documentation. 

## _MS45xx Series Application Note_ 

- Bypass Capacitor Selection 

- Pressure Hose Recommendations 

- PCB Layout Recommendations 

## _Interfacing to MEAS Digital Pressure Modules_ 

- I[2] C or SPI Protocol Description 

- Data Fetch, Measurement Request Commands 

- Timing Diagrams 

## _Configuration, POR and Power Consumption_ 

- Standard and Low Power Configuration 

- Power On Reset (POR) 

- Current Consumption by Sampling Frequency 

## AVAILABLE OPTIONS 

## **Gel Coat (-F Option)** 

The MS4525DO is designed for non-ionic and clean dry air applications.  Select this option for added protection in high humidity or slightly corrosive environments with the application of a silicone gel elastomer to sensor and ASIC.  For questions concerning media compatibility, contact the factory. 

## **Low Power (-L Option)** 

Select this option for battery powered or handheld device applications.  In this configuration, the sensor and calibration microcontroller are powered down, drawing a current of ~ 0.6uA (Vs=5.0 VDC).  When the master sends a **Read MR** (measurement request) command (I[2] C or SPI); the sensor is “awaken” and begins the measurement cycle; data is then placed onto the output registers.  The sensor and calibration microcontroller are powered down again, awaiting the **Read DF** (data fetch) command from the master.
