The MS4515DO is a small, ceramic based, PCB mounted pressure transducer from TE Connectivity.  The transducer is built using 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 MS4515DO is fully calibrated and temperature compensated with a total error band (TEB) of less than 1.0% over the compensated range. The sensor operates from single supply of either 3.3 or 5.0VDC and requires a single external component for proper operation. 

- Medical Instruments 

- Fire Suppression System 

- Panel Meter 

- Air Movement/Environmental Controls 

- Pneumatic Controls 

The rugged ceramic transducer is available in side port, top port, and manifold mount and can measure gage or differential pressure from 2 to 30 inches H2O. 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. 

## CONNECTION DIAGRAM 

## **Notes** 

1. Place 100nF capacitor between Supply and GND to within 2 cm of sensor.

## AVAILABLE OPTIONS 

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

The MS4515DO 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.
